This monitor has disappointing HDR peak brightness. The cluster latency distribution has a long tail, so that querying more servers increases the query overall latency. High values are preferable for long-running non-interactive queries because it allows them to quickly give up resources in favour of short interactive queries when they arrive. Sets the character that is interpreted as a delimiter before the field of the first column for CustomSeparated data format. For more information about ranges of data in MergeTree tables, see MergeTree. This is a setting that's becoming more and more common, though it still isn't exactly universal. Regexp of column names of type String to output as Avro string (default is bytes). Table 2: Summarizes settings for watching video. RELATED: How To Use An Xbox One Controller On Android or iOS. Batch sending improves cluster performance by better-utilizing server and network resources. This setting applies to all concurrently running queries on the server. This is a setting that's becoming more and more common, though it still isn't exactly universal. If the distance between two data blocks to be read in one file is less than merge_tree_min_rows_for_seek rows, then ClickHouse does not seek through the file but reads the data sequentially. This is the step where the video processor sends the image to the screen. This behaviour exists to enable the insertion of highly aggregated data into materialized views, for cases where inserted blocks are the same after materialized view aggregation but derived from different INSERTs into the source table. We need to scatter their data on the fly during distributed processing with the GLOBAL keyword GLOBAL IN/GLOBAL JOIN. However, the VESA mounting holes don't line up with the display's center of gravity, causing the display to tilt downwards when VESA-mounted. Windows-managed core parking can put CPU cores to sleep too often, which may increase frametime variances and spikes. For not replicated tables see non_replicated_deduplication_window. Merges happen in the usual way on all the replicas. Blocks the size of max_block_size are not always loaded from the table. Meanwhile, as buffer A finishes scanning its first frame, buffer B begins to render frame B, and upon completion, scans it to the display, repeat. If it is set to true, allow strings in single quotes. If column type is nullable, then NULL values are inserted as is, regardless of this setting. Limits sizes of right-hand join data blocks in partial merge join algorithm for JOIN queries. The last query is equivalent to the following: Enables or disables template deduction for SQL expressions in Values format. Once again, the 'Off' and 'Normal' Over Drive settings are so similar and they're better than 'Extreme', so we still suggest using 'Normal'. If the async_insert_stale_timeout_ms is set to a non-zero value, the data is inserted after async_insert_stale_timeout_ms milliseconds since the last query. Predicate pushdown may significantly reduce network traffic for distributed queries. Suitable for scenarios that pursue performance and do not require persistence. The Acer XV282K has great response times at 60Hz. 0 The query will be displayed without table UUID. ClickHouse can parse the basic YYYY-MM-DD HH:MM:SS format and all ISO 8601 date and time formats. Stephen is an avid Nintendo, Indie, and retro gamer who dabbles in Xbox, mainly in the form of binge sessions of Overwatch. It has fantastic ergonomics, so there won't be issues placing it in an ideal viewing position, and it has wide viewing angles if you need to share your screen with a coworker. 1 Formatted queries are logged in the system table. The bigger the value of the setting, the more RAM used and the less disk I/O needed. Removing all the image processing and Smart TV functions from competing OLED TVs helped reduce the input lag to super low levels which was great news. VRR doesn't work properly on the desktop, though, and in-game, it only works well if your computer can maintain a high frame rate. The following types of queries are supported (and all combinations of them): The following types of queries are not supported (support for some of them may be added later): Right now it requires optimize_skip_unused_shards (the reason behind this is that one day it may be enabled by default, and it will work correctly only if data was inserted via Distributed table, i.e. Sets the period for a real clock timer of the query profiler. External FPS Limiters, 12 G-SYNC 101: External FPS Limiter HOWTO, 13 G-SYNC 101: Hidden Benefits of High Refresh Rate G-SYNC, 14 G-SYNC 101: Optimal G-SYNC Settings & Conclusion. Controls force_optimize_skip_unused_shards (hence still requires force_optimize_skip_unused_shards) depends on the nesting level of the distributed query (case when you have Distributed table that look into another Distributed table). By default: 1,000,000. Default value: 30000 milliseconds (30 seconds). Consider the following table account_orders: When output_format_json_quote_denormals = 0, the query returns null values in output: When output_format_json_quote_denormals = 1, the query returns: Controls quoting of decimals in JSON output formats. Path to file which contains format string for result set (for Template format). The Acer has lower input lag at 60Hz,for a more responsive gaming experience from older devices, and it has better ergonomics. Positive floating-point number in the range. The HDR brightness is okay. To prevent the use of any replica with a non-zero lag, set this parameter to 1. Dropping whole parts instead of partial cleaning TTL-d rows allows having shorter merge_with_ttl_timeout times and lower impact on system performance. For example, members of a Tuple or subcolumns of a Map, Nullable or an Array data type. This is, however, an approximation because your computer doesn't necessarily output both signals at once. It has excellent coverage of the DCI P3 color space used in most HDR content. The Samsung supports HDR, which the MSI doesn't, but it doesn't add much because it can't display a wide color gamut. The list of column names and types to use as hints in schema inference for formats without schema. The Acer Nitro XV282K KVbmiipruzx is an excellent gaming monitor. This gives more control to rebalance query workloads among replicas. There's one subtle-yet-significant factor that some gamers neglect; input lag. The Samsung Odyssey G5 is mediocre for office use. Sets the heartbeat interval in seconds to indicate live view is alive . The difference between enabled and disabled: Note that this setting influences Materialized view and MaterializedMySQL behaviour. Sets the period for a CPU clock timer of the query profiler. The Samsung Odyssey Ark is the most absurd and amazing gaming monitor. Driven by data, run by a passionate team of engineers, testers, technical writers, developers, and more. If that's the case, try using wired connections or use USB receivers if your wireless mice and keyboards come with them because their latency is a lot lower than Bluetooth. This setting takes ClickHouse version number as a string, like 21.3, 21.8. The Acer Nitro XV282K KVbmiipruzx is a bit better than the LG 27GP950-B. You can also limit the speed for a particular table with max_replicated_fetches_network_bandwidth setting. On the other hand, the Gigabyte has a faster response time at 60Hz, better black uniformity, and a more versatile black frame insertion feature. Table 1: Summarizes settings for PC/Console gaming. Overall, it's well-built, and there aren't too many glaring issues, but there's nothing premium about it either. TheMSI Optix G27CQ4 and the Samsung Odyssey G5 LC27G55T are both good gaming monitors. It has native FreeSync variable refresh rate (VRR) support, very quick response times, and low input lag for a responsive gaming experience. Any other game that always sits well above that 165 mark would then automatically have G-SYNC disengaged and would play like normal? The ASUS ProArt Display PA278QV is much better than the Samsung Odyssey G5 LC27G55T; however, they aren't intended for the same use. You can watch the latest 4k videos online thanks to its high resolution, and the 28 inch screen provides an immersive viewing experience. Use ORC String type instead of Binary for String columns. Set up G-SYNC > Enable G-SYNC, G-SYNC Compatible > Enable for full screen mode. We test for the input lag at its native resolution using different refresh rates and settings available. Driven by data, run by a passionate team of engineers, testers, technical writers, developers, and more. With this setting NULL = NULL returns true for IN operator. G-SYNC Windowed Mode Enable for windowed and full screen mode allows G-SYNC support for windowed and borderless windowed mode. User can set any string as a value, for example, My NULL. The query is sent to the replica with the fewest errors, and if there are several of these, to anyone of them. The biggest feature or adjustment when it comes to cutting back on input lag, is, not surprisingly, "Game Mode." AMD Radeon FreeSync keeps your monitor and graphics card refresh rate in sync to reduce image tearing. Motion looks smooth thanks to the near-instantaneous response time, and it has low input lag with high-frame-rate signals, but it increases a bit with lower-frame-rate signals. There's also a larger variant with a 21:9 aspect ratio and 34 inch screen, the Samsung Odyssey G5 LC34G55T. The top button is to power the monitor On/Off. It has very good color accuracy, wide viewing angles, and a great resolution that will display every little detail. Use schema from cache for URL with last modification time validation (for urls with Last-Modified header). Enables or disables sequential consistency for SELECT queries. 0 Identical aggregate expressions are always JIT-compiled. The Samsung Odyssey G5 has a good contrast ratio, so blacks look black in a dark room instead of gray. When it comes to gaming, they both have exceptionally fast response times and low input lag. If a replica's lag is greater than or equal to the set value, this replica is not used. The Samsung Odyssey G5 is a good gaming monitor. For more information about data ranges in MergeTree tables, see MergeTree. The first_or_random algorithm solves the problem of the in_order algorithm. If enabled, the data is combined into batches before the insertion into tables, so it is possible to do small and frequent insertions into ClickHouse (up to 15000 queries per second) without buffer tables. 1 Creating several dictionaries for the data part is prohibited. ClickHouse configuration file contains a wrong hostname. Ive seen reports that some models may have a less immediate scanout when disabled (VRR requires a near-instantaneous scanout to function properly, whereas a fixed refresh rate doesnt), and/or affect overdrive preset appearance, but, again, that can vary heavily based on the given model/firmware implementation. I understand G-SYNC will disengage past 165 FPS, and my setup would act exactly as if I had G-SYNC disabled in NVCP? Removing all the image processing and Smart TV functions from competing OLED TVs helped reduce the input lag to super low levels which was great news. Not too bad considering this is more or less a peripheral feature that's not very crucial. It's also not very accurate because it depends on your camera's shutter speed and whether you can capture the correct frame with the time on it. Expressions for some column may have the same structure, but contain numeric literals of different types, e.g. Learn how your comment data is processed. It also supports HDR, which the G3 doesn't, but it doesn't add much because it has low HDR peak brightness and can't display a wide color gamut. There are many ways to control brightness of a monitor, laptop or integrated panel (such as the iMac). For example, '2018-06-08T01:02:03.000Z'. Enables or disables checking the column order when inserting data. The feature is mainly for AggregatingMergeTree and is not heavily tested. Use DOC/Windows-style line separator (CRLF) in TSV instead of Unix style (LF). For complex default expressions input_format_defaults_for_omitted_fields must be enabled too. It also has a better SDR and HDR color gamut, and it gets a lot brighter. This setting applies to every individual query. The G-SYNC module is a small chip that replaces the displays standard internal scaler, and contains enough onboard memory to hold and process a single frame at a time. There's no definitive amount of input lag when people will start noticing it because everyone is different. 0 Projection optimization is not obligatory. A lower setting triggers selecting tasks in background_schedule_pool frequently, which results in a large number of requests to ClickHouse Keeper in large-scale clusters. For not replicated tables see non_replicated_deduplication_window. It has outstanding low input lag, but unfortunately, it doesn't support any of the variable refresh rate technologies, like AMD's FreeSync. As to whether it affects anything else, thats model dependent. When the input_format_tsv_enum_as_number setting is enabled: When the input_format_tsv_enum_as_number setting is disabled: Use some tweaks and heuristics to infer schema in TSV format. The total input lag time is the addition of threeparts. Similar to the ASUS VG279QM, the input lag significantly increases at 60Hz. Note that output is in UTC (Z means UTC). G-SYNC off + V-SYNC off + FPS limit above the refresh rate that does not max GPU usage (to avoid further render queue latency unrelated to G-SYNC or V-SYNC) or Reflex (which does the same thing automatically without need of a manual FPS limit). I had a quick question about G-SYNC usage in specific games. Specifies the algorithm of replicas selection that is used for distributed query processing. user can avoid the same inserted data being deduplicated. Be aware however, that LLM On doesnt always work in every game either, and not in DX12 or Vulkan at all. G-SYNC off + V-SYNC off + FPS limit above the refresh rate that does not max GPU usage (to avoid further render queue latency unrelated to G-SYNC or V-SYNC) or Reflex (which does the same thing automatically without need of a manual FPS limit). Zero means skip the query. It has exceptional gradient handling and can display a wide color gamut, making it a great choice for media creation. VRR behavior will disengage with G-SYNC on + V-SYNC off whenever the framerate is above the refresh rate, but it will obviously re-engage during any major frametime variances or more demanding scenes that drop the average framerate below the refresh rate. The LG 27GP83B is a great monitor for pretty much any usage. Discord is constantly updating, so the newest release might present a solution to your lag spike. Sets the time in seconds. The LG 27GP83B is a great monitor for pretty much any usage. The direct algorithm performs a lookup in the right table using rows from the left table as keys. On the other hand, the 27GN750-B is a 1080p monitor with a much higher 240Hz refresh rate, slightly lower input lag, and it Even with local dimming enabled, our test pattern doesn't trigger any dimming zones, so it looks the same. Limits the speed that data is exchanged at over the network in bytes per second. ClickHouse applies this setting when the query contains the product of distributed tables, i.e. There's significant backlight bleed and clouding throughout, and the screen looks closer to gray due to the low contrast. The LG has an IPS panelwith wider viewing angles, making it better for sharing content or playing co-op games, but it isn't as ideal for dark rooms as the Samsung because it has a low contrast ratio that makes blacks appear gray. Heres how to update Discord: Find the Discord app on the taskbar. It helps to reduce the load with a large volume of queries in a second. Input lag on a monitor is the time it takes the monitor to display an image on the screen from when it receives the signal. After calibration, the accuracy is remarkable. This setting is applied at the ClickHouse server start and cant be changed in a user session. If a behaviour in ClickHouse was changed by using a different default value for some setting, this compatibility setting allows you to use default values from previous versions for all the settings that were not set by the user. To use this setting, you need to set the CAP_SYS_NICE capability. When batch sending is enabled, the Distributed table engine tries to send multiple files of inserted data in one operation instead of sending them separately. Sets the number of threads performing background tasks for message streaming. If wait_for_async_insert is enabled, every client will wait for the data to be processed and flushed to the table. TheSamsung Odyssey G5 S27AG50 is an updated version of theSamsung Odyssey G5 LC27G55T, but they're different monitors. When it comes to gaming, they both have exceptionally fast response times and low input lag. Sets the maximum URI length of an HTTP request. On monitors, most people are just using their PCs, and there aren't as many image processing settings, so we don't need to test those. So if I use Max Frame rate on the NVCP I should set LLM to on? The Acer Nitro XV282K supports most currently supported resolutions and features from the PS5. The Samsung Odyssey Ark is the most absurd and amazing gaming monitor. Enables or disables introspections functions for query profiling. Enables or disables parallelism for quorum INSERT queries. so that you can compare the results easily. Once the monitor has processed the image, it's ready to be displayed on the screen. When enabled, replace empty input fields in CSV with default values. Unfortunately, the response time and input lag are much worse at 60Hz. It adjusts the value set by the LIMIT clause, so that the limit, specified in the query, cannot exceed the limit, set by this setting. Path to file which contains format string for rows (for Template format). It also has a low input lag and supports VRR to reduce screen tearing. Since its HDMI ports require DSC to achieve the maximum bandwidth possible, which the PS5 doesn't fully support, the image is limited to chroma 4:2:0. The INSERT query also contains data for INSERT that is processed by a separate stream parser (that consumes O(1) RAM), which is not included in this restriction. If this is a gift, consider delivery to a different address. On the other hand, the Gigabyte gets brighter, making it a better choice for well-lit rooms, and its response time at 60Hz is quicker, so motion looks smoother. The response time is only decent and you may notice some motion blur, but it has a Black Frame Insertion feature to help improve the appearance of motion. Having trouble deciding between two monitors? Cancels HTTP read-only queries (e.g. It has exceptional gradient handling and can display a wide color gamut, making it a great choice for media creation. For production usage with frequent small insertions or slow ZooKeeper cluster it is recommended to use default value. Tarkov seriously feels like an entirely different game with G-SYNC and im not even sure why. In this case, clickhouse-server shows a message about it at the start. If you want your manually set MFR limit to consistently apply instead of the Ultra auto limit (which, again, isnt always guaranteed to engage in a game), then yes you can set LLM to On.. Works for tables with streaming in the case of a timeout, or when a thread generates max_insert_block_size rows. It's a bit worse than the LG 27GP950-B when gaming at 60Hz, but it isn't noticeable. Changelog. Defines the maximum number of values generated by function per block of data (sum of array sizes for every row in a block). Supported only for TSV, TKSV, CSV and JSONEachRow formats. On the other hand, the S24AG30 has much better contrast, but this can vary between units. When writing data, ClickHouse throws an exception if input data contain columns that do not exist in the target table. The easiest way you can measure input lag is by connecting a computer to two different screens (a base screen and the test screen). Our HDR measurement represents the amount of input lag present when a monitor is displaying HDR content. Possible values: Positive integer. To improve insert performance, we recommend disabling this check if you are sure that the column order of the input data is the same as in the target table. Enables or disables fsync when writing .sql files. From the front, the Samsung Odyssey G5 looks similar to its bigger sibling, the Samsung Odyssey G7 LC32G75T, with thin borders on three sides and a wide V-shaped stand. If the number of rows to be read from a file of a MergeTree table exceeds merge_tree_min_rows_for_concurrent_read then ClickHouse tries to perform a concurrent reading from this file on several threads. Monitors store-bought and tested, supported by you via. I understand G-SYNC will disengage past 165 FPS, and my setup would act exactly as if I had G-SYNC disabled in NVCP? TABLE OF CONTENTS. If a query from the same user with the same query_id already exists at this time, the behaviour depends on the replace_running_query parameter. Ithas better ergonomics because it allows for height adjustment, and the viewing angles are better, quite good for a VA panel. Perfect for gaming! The setting isn't followed perfectly accurately. The Samsung Odyssey G5 has exceptionally low input lag, but it's significantly higher when playing at 60Hz. This monitor has superb gradient handling. When the setting is disabled, the result always has the destination type exactly. The ASUS VG258QM is an excellent gaming monitor. Most saturated colors are over-saturated a bit, and there's no sRGB mode to clamp them to the sRGB primaries. A few examples: The time this step takes is affected by the speed of the video processor and the total amount of processing. Find the perfect Monitors for you! Sets a maximum size in rows of a shared global dictionary for the LowCardinality data type that can be written to a storage file system. The Acer Nitro XV282K KVbmiipruzx and the Samsung Odyssey G7 S28AG70 are both excellent 4k gaming monitors. If ClickHouse should read more than merge_tree_max_rows_to_use_cache rows in one query, it does not use the cache of uncompressed blocks. Sets the compression codec used for output Avro file. Hi jorimt. temporary disables distributed_directory_monitor_batch_inserts for failed batches). The Dell AW3423DW is excellent for gaming. They each have HDMI 2.1 inputs, but the Samsung supports a higher bandwidth, so it doesn't require compression for 4k @ 120 fps games like on the Acer. When using the hash algorithm, the right part of JOIN is uploaded into RAM. It also has a faster response time, but gaming feels smoother and more responsive on the Samsung due to its higher refresh rate. Basically, both LLM On and Ultra are pointless in virtually all respects if, for instance, youre playing a DX12 game that supports Reflex (which is LLMs replacement). See an example for the DESCRIBE statement. Hi jorimt. Enables or disables throwing an exception in the pointInPolygon function, if the polygon is self-intersecting or self-tangent. Max rows in a file (if permitted by storage). By default, 0 (disabled). *Settings tested with a single G-SYNC display (w/hardware module) on a single desktop GPU system; specific DSR, SLI, and multi-monitor behaviors, as well as G-SYNC laptop display and G-SYNC Compatible display implementation, may vary. Any remaining inaccuracies to the white balance and colors are nearly impossible to spot by the human eye and the color temperature is extremely close to our 6500K target. The reflection handling of this monitor is good. If disabled, all fields will be treated as String. Its effective in cross-replication topology setups, but useless in other configurations. It has a quick response time, high refresh rate, and low input lag, resulting in a smooth and responsive gaming experience. Used for the same purpose as max_block_size, but it sets the recommended block size in bytes by adapting it to the number of rows in the block. Input lag isn't dependent on the refresh rate, but having a high refresh rate can help lower the input lag. Do not enable this feature in version <= 21.8. The following parameters are only used when creating Distributed tables (and when launching a server), so there is no reason to change them at runtime. This value is used to compute overcommit ratio for the query. 0 Insertions are made synchronously, one after another. If enable_optimize_predicate_expression = 1, then the execution time of these queries is equal because ClickHouse applies WHERE to the subquery when processing it. Although the Acer Nitro XV282K KVbmiipruzx supports HDMI 2.1, it's limited to 24Gbps, and relies on Display Stream Compression (DSC) 1.2a for anything that requires higher bandwidth. This setting helps to reduce the number of calls to external sources while joining such tables: only one call per query. The LG 27GL650F-B is good for most uses. All the data that cant be encoded due to maximum dictionary size limitation ClickHouse writes in an ordinary method. TheSamsung Odyssey G5 LC34G55Tis a larger variant of the Samsung Odyssey G5 LC27G55Twith a 34 inch screen and 21:9 aspect ratio. People don't watch content from one source using the same settings, as they often change their settings and sources with TVs, and with that comes different input lag. Given that, for example, dictionaries, can be out of sync across nodes, mutations that pull values from them are disallowed on replicated tables by default. On the other hand, the LC27G55T's BFI feature works at a much wider range, and it has built-in speakers, which the S27AG50 doesn't. That means the impact could spread far beyond the agencys payday lending rule. Short for "HDMI Consumer Electronics Control", this setting is a feature that provides compatibility with other devices. so that you can compare the results easily. Most monitors have low enough input lag that you won't notice any delay during regular desktop use. When writing 8192 rows, the average will be slightly less than 500 KB of data. Learn how your comment data is processed. Application-controlled adheres to the desktops current refresh rate, or defers control to games that contain a refresh rate selector. Skip lines unmatched by regular expression. Picture quality looks similar between both, and even though the Samsung has a slightly bigger screen, text looks sharp on each. Similar to the ASUS VG279QM, the input lag significantly increases at 60Hz. Sets the time in seconds. Also, they use different panels; the Acer has an IPS panel with wide viewing angles, while the Samsung has a VA panel with better contrast. The Acer Nitro XV282K KV is excellent for gaming. Enables or disables the deduplication check for materialized views that receive data from Replicated* tables. It's done the same way as the other tests but with a 60Hz signal. The ASUS ROG Strix XG279Q has an incredibly low input lag at its max refresh rate of 170Hz. Just looking to have the cleanest setup to use G-SYNC in the games I choose, and completely clean in the games I do not need it in. fallback_to_stale_replicas_for_distributed_queries, http_native_compression_disable_checksumming_on_decompress, merge_tree_min_rows_for_concurrent_read_for_remote_filesystem, merge_tree_min_bytes_for_concurrent_read_for_remote_filesystem, max_replica_delay_for_distributed_queries, connect_timeout, receive_timeout, send_timeout, cancel_http_readonly_queries_on_client_close, max_replicated_fetches_network_bandwidth_for_server, max_replicated_sends_network_bandwidth_for_server, deduplicate_blocks_in_dependent_materialized_views, allow_nondeterministic_optimize_skip_unused_shards, force_optimize_skip_unused_shards_nesting, distributed_directory_monitor_max_sleep_time_ms, distributed_directory_monitor_batch_inserts, distributed_directory_monitor_split_batch_on_failure, use_compact_format_in_distributed_parts_names, background_buffer_flush_schedule_pool_size, background_distributed_schedule_pool_size, background_message_broker_schedule_pool_size, low_cardinality_use_single_dictionary_for_part, min_insert_block_size_rows_for_materialized_views, min_insert_block_size_bytes_for_materialized_views, execute_merges_on_single_replica_time_threshold, database_atomic_wait_for_drop_and_detach_synchronously, show_table_uuid_in_table_create_query_if_not_nil, max_live_view_insert_blocks_before_refresh, database_replicated_initial_query_timeout_sec, replication_wait_for_inactive_replica_timeout, enable_extended_results_for_datetime_functions, memory_usage_overcommit_max_wait_microseconds, memory_overcommit_ratio_denominator_for_user, schema_inference_use_cache_for_file {schema_inference_use_cache_for_file}, schema_inference_use_cache_for_s3 {schema_inference_use_cache_for_s3}, schema_inference_use_cache_for_url {schema_inference_use_cache_for_url}, schema_inference_use_cache_for_hdfs {schema_inference_use_cache_for_hdfs}, schema_inference_cache_require_modification_time_for_url, input_format_max_rows_to_read_for_schema_inference, input_format_ipv4_default_on_conversion_error, input_format_ipv6_default_on_conversion_error, input_format_json_read_numbers_as_strings, input_format_json_validate_types_from_metadata, output_format_json_escape_forward_slashes, output_format_json_named_tuples_as_objects, format_json_object_each_row_column_for_object_name, input_format_tsv_use_best_effort_in_schema_inference, input_format_csv_use_best_effort_in_schema_inference, input_format_values_deduce_templates_of_expressions, input_format_values_accurate_types_of_literals, input_format_arrow_case_insensitive_column_matching, input_format_arrow_skip_columns_with_unsupported_types_in_schema_inference, output_format_arrow_low_cardinality_as_dictionary, input_format_orc_case_insensitive_column_matching, input_format_orc_skip_columns_with_unsupported_types_in_schema_inference, input_format_parquet_case_insensitive_column_matching, input_format_parquet_allow_missing_columns, input_format_parquet_skip_columns_with_unsupported_types_in_schema_inference, input_format_hive_text_collection_items_delimiter, input_format_hive_text_map_keys_delimiter, output_format_msgpack_uuid_representation, input_format_protobuf_flatten_google_wrappers, output_format_protobuf_nullables_with_google_wrappers, output_format_pretty_max_column_pad_width, CustomSeparated format settings {custom-separated-format-settings}, input_format_mysql_dump_table_name (#input_format_mysql_dump_table_name), input_format_mysql_dump_map_columns (#input_format_mysql_dump_map_columns), SQLInsert format settings {$sqlinsert-format-settings}, output_format_sql_insert_include_column_names.
