UserSettings

Field	Description
readonly	google.protobuf.Int64Value Restricts permissions for non-DDL queries. To restrict permissions for DDL queries, use allow_ddl instead. 0 (default)-no restrictions. 1-only read data queries are allowed. 2-read data and change settings queries are allowed. See in-depth description in ClickHouse documentation. Acceptable values are 0 to 2, inclusive.
allow_ddl	google.protobuf.BoolValue Determines whether DDL queries are allowed (e.g., CREATE, ALTER, RENAME, etc). Default value: true. See in-depth description in ClickHouse documentation.
insert_quorum	google.protobuf.Int64Value Enables or disables write quorum for ClickHouse cluster. If the value is less than 2, then write quorum is disabled, otherwise it is enabled. When used, write quorum guarantees that ClickHouse has written data to the quorum of insert_quorum replicas with no errors until the insert_quorum_timeout expires. All replicas in the quorum are in the consistent state, meaning that they contain linearized data from the previous INSERT queries. Employ write quorum, if you need the guarantees that the written data would not be lost in case of one or more replicas failure. You can use select_sequential_consistency setting to read the data written with write quorum. See in-depth description in ClickHouse documentation. The minimum value is 0.
connect_timeout	google.protobuf.Int64Value Connection timeout in milliseconds. Value must be greater than 0 (default: 10000, 10 seconds). Value must be greater than 0.
receive_timeout	google.protobuf.Int64Value Receive timeout in milliseconds. Value must be greater than 0 (default: 300000, 300 seconds or 5 minutes). Value must be greater than 0.
send_timeout	google.protobuf.Int64Value Send timeout in milliseconds. Value must be greater than 0 (default: 300000, 300 seconds or 5 minutes). Value must be greater than 0.
insert_quorum_timeout	google.protobuf.Int64Value Quorum write timeout in milliseconds. If the write quorum is enabled in the cluster, this timeout expires and some data is not written to the insert_quorum replicas, then ClickHouse will abort the execution of INSERT query and return an error. In this case, the client must send the query again to write the data block into the same or another replica. Minimum value: 1000, 1 second (default: 60000, 1 minute). The minimum value is 1000.
select_sequential_consistency	google.protobuf.BoolValue Determines the behavior of SELECT queries from the replicated table: if enabled, ClickHouse will terminate a query with error message in case the replica does not have a chunk written with the quorum and will not read the parts that have not yet been written with the quorum. Default value: false (sequential consistency is disabled).
max_replica_delay_for_distributed_queries	google.protobuf.Int64Value Max replica delay in milliseconds. If a replica lags more than the set value, this replica is not used and becomes a stale one. Minimum value: 1000, 1 second (default: 300000, 300 seconds or 5 minutes). See in-depth description in ClickHouse documentation. The minimum value is 1000.
fallback_to_stale_replicas_for_distributed_queries	google.protobuf.BoolValue Enables or disables query forcing to a stale replica in case the actual data is unavailable. If enabled, ClickHouse will choose the most up-to-date replica and force the query to use the data in this replica. This setting can be used when doing SELECT query from a distributed table that points to replicated tables. Default value: true (query forcing is enabled). See in-depth description in ClickHouse documentation.
replication_alter_partitions_sync	google.protobuf.Int64Value Wait mode for asynchronous actions in ALTER queries on replicated tables: 0-do not wait for replicas. 1-only wait for own execution (default). 2-wait for all replicas. See in-depth description in ClickHouse documentation. Acceptable values are 0 to 2, inclusive.
distributed_product_mode	enum DistributedProductMode Determine the behavior of distributed subqueries. See in-depth description in ClickHouse documentation. DISTRIBUTED_PRODUCT_MODE_DENY: Default value. Prohibits using these types of subqueries (returns the "Double-distributed in/JOIN subqueries is denied" exception). DISTRIBUTED_PRODUCT_MODE_LOCAL: Replaces the database and table in the subquery with local ones for the destination server (shard), leaving the normal IN/JOIN. DISTRIBUTED_PRODUCT_MODE_GLOBAL: Replaces the IN/JOIN query with GLOBAL IN/GLOBAL JOIN. DISTRIBUTED_PRODUCT_MODE_ALLOW: Allows the use of these types of subqueries.
distributed_aggregation_memory_efficient	google.protobuf.BoolValue Enables of disables memory saving mode when doing distributed aggregation. When ClickHouse works with a distributed query, external aggregation is done on remote servers. Enable this setting to achieve a smaller memory footprint on the server that sourced such a distributed query. Default value: false (memory saving mode is disabled). See in-depth description in ClickHouse documentation.
distributed_ddl_task_timeout	google.protobuf.Int64Value Timeout for DDL queries, in milliseconds.
skip_unavailable_shards	google.protobuf.BoolValue Enables or disables silent skipping of unavailable shards. A shard is considered unavailable if all its replicas are also unavailable. Default value: false (silent skipping is disabled). See in-depth description in ClickHouse documentation.
compile	google.protobuf.BoolValue Enables or disables query compilation. If you execute a lot of structurally identical queries, then enable this setting. As a result, such queries may be executed faster due to use of queries' compiled parts. Use this setting in combination with min_count_to_compile setting. Default value: false (compilation is disabled). See in-depth description in ClickHouse documentation.
min_count_to_compile	google.protobuf.Int64Value How many structurally identical queries ClickHouse has to encounter before they are compiled. Minimum value: 0 (default: 3). For the 0 value compilation is synchronous: a query waits for compilation process to complete prior to continuing execution. It is recommended to set this value only for testing purposes. For all other values, compilation is asynchronous: the compilation process executes in a separate thread. When a compiled part of query is ready, it will be used by ClickHouse for eligible queries, including the ones that are currently running. See in-depth description in ClickHouse documentation. The minimum value is 0.
compile_expressions	google.protobuf.BoolValue Enables or disables expression compilation. If you execute a lot of queries that contain identical expressions, then enable this setting. As a result, such queries may be executed faster due to use of compiled expressions. Use this setting in combination with min_count_to_compile_expression setting. Default value: false (expression compilation is disabled).
min_count_to_compile_expression	google.protobuf.Int64Value How many identical expressions ClickHouse has to encounter before they are compiled. Minimum value: 0 (default: 3). For the 0 value compilation is synchronous: a query waits for expression compilation process to complete prior to continuing execution. It is recommended to set this value only for testing purposes. For all other values, compilation is asynchronous: the compilation process executes in a separate thread. When a compiled expression is ready, it will be used by ClickHouse for eligible queries, including the ones that are currently running. The minimum value is 0.
max_block_size	google.protobuf.Int64Value The maximum block size for reading. Data in ClickHouse is organized and processed by blocks (block is a set of columns' parts). The internal processing cycles for a single block are efficient enough, but there are noticeable expenditures on each block. This setting is a recommendation for size of block (in a count of rows) that should be loaded from tables. Value must be greater than 0 (default: 65536). See in-depth description in ClickHouse documentation. Value must be greater than 0.
min_insert_block_size_rows	google.protobuf.Int64Value Limits the minimum number of rows in a block to be inserted in a table by INSERT query. Blocks that are smaller than the specified value, will be squashed together into the bigger blocks. Minimal value: 0, block squashing is disabled (default: 1048576). The minimum value is 0.
min_insert_block_size_bytes	google.protobuf.Int64Value Limits the minimum number of bytes in a block to be inserted in a table by INSERT query. Blocks that are smaller than the specified value, will be squashed together into the bigger blocks. Minimal value: 0, block squashing is disabled (default: 268435456, 256 MB). The minimum value is 0.
max_insert_block_size	google.protobuf.Int64Value Allows to form blocks of the specified size (in bytes) when inserting data in a table. This setting has effect only if server is creating such blocks by itself. Value must be greater than 0 (default: 1048576). See in-depth description in ClickHouse documentation. Value must be greater than 0.
min_bytes_to_use_direct_io	google.protobuf.Int64Value Limits the minimum number of bytes to enable unbuffered direct reads from disk (Direct I/O). By default, ClickHouse does not read data directly from disk, but relies on the filesystem and its cache instead. Such reading strategy is effective when the data volume is small. If the amount of the data to read is huge, it is more effective to read directly from the disk, bypassing the filesystem cache. If the total amount of the data to read is greater than the value of this setting, then ClickHouse will fetch this data directly from the disk. Minimal value and default value: 0, Direct I/O is disabled. The minimum value is 0.
use_uncompressed_cache	google.protobuf.BoolValue Determines whether to use the cache of uncompressed blocks, or not. Using this cache can significantly reduce latency and increase the throughput when a huge amount of small queries is to be processed. Enable this setting for the users who instantiates small queries frequently. This setting has effect only for tables of the MergeTree family. Default value: false (uncompressed cache is disabled). See in-depth description in ClickHouse documentation.
merge_tree_max_rows_to_use_cache	google.protobuf.Int64Value Limits the maximum size in rows of the request that can use the cache of uncompressed data. The cache is not used for requests larger than the specified value. Use this setting in combination with use_uncompressed_cache setting. Value must be greater than 0 (default: 128x8192). Value must be greater than 0.
merge_tree_max_bytes_to_use_cache	google.protobuf.Int64Value Limits the maximum size in bytes of the request that can use the cache of uncompressed data. The cache is not used for requests larger than the specified value. Use this setting in combination with use_uncompressed_cache setting. Value must be greater than 0 (default: 192x10x1024x1024). Value must be greater than 0.
merge_tree_min_rows_for_concurrent_read	google.protobuf.Int64Value Limits the minimum number of rows to be read from a file to enable concurrent read. If the number of rows to be read exceeds this value, then ClickHouse will try to use a few threads to read from a file concurrently. This setting has effect only for tables of the MergeTree family. Value must be greater than 0 (default: 20x8192). Value must be greater than 0.
merge_tree_min_bytes_for_concurrent_read	google.protobuf.Int64Value Limits the number of bytes to be read from a file to enable concurrent read. If the number of bytes to be read exceeds this value, then ClickHouse will try to use a few threads to read from a file concurrently. This setting has effect only for tables of the MergeTree family. Value must be greater than 0 (default: 24x10x1024x1024). Value must be greater than 0.
max_bytes_before_external_group_by	google.protobuf.Int64Value Sets the threshold of RAM consumption (in bytes) after that the temporary data, collected during the GROUP BY operation, should be flushed to disk to limit the RAM comsumption. By default, aggregation is done by employing hash table that resides in RAM. A query can result in aggregation of huge data volumes that can lead to memory exhaustion and abortion of the query (see the max_memory_usage setting). For such queries, you can use this setting to force ClickHouse to do flushing and complete aggregation successfully. Minimal value and default value: 0, GROUP BY in the external memory is disabled. When using aggregation in external memory, it is recommended to set the value of this setting twice as low as the max_memory_usage setting value (by default, the maximum memory usage is limited to ten gigabytes). See in-depth description in ClickHouse documentation. See also: the distributed_aggregation_memory_efficient setting.
max_bytes_before_external_sort	google.protobuf.Int64Value This setting is equivalent of the max_bytes_before_external_group_by setting, except for it is for sort operation (ORDER BY), not aggregation.
group_by_two_level_threshold	google.protobuf.Int64Value Sets the threshold of the number of keys, after that the two-level aggregation should be used. Minimal value: 0, threshold is not set (default: 10000).
group_by_two_level_threshold_bytes	google.protobuf.Int64Value Sets the threshold of the number of bytes, after that the two-level aggregation should be used. Minimal value: 0, threshold is not set (default: 100000000).
priority	google.protobuf.Int64Value Sets the priority of a query. 0-priority is not used. 1-the highest priority. and so on. The higher the number, the lower a query's priority. This setting should be set up for each query individually. If ClickHouse is working with the high-priority queries, and a low-priority query enters, then the low-priority query is paused until higher-priority queries are completed. Minimal value and default value: 0, priority is not used. The minimum value is 0.
max_threads	google.protobuf.Int64Value Limits the maximum number of threads to process the request (setting does not take threads that read data from remote servers into account). This setting applies to threads that perform the same stages of the query processing pipeline in parallel. Minimal value and default value: 0 (the thread number is calculated automatically based on the number of physical CPU cores, no HyperThreading cores are taken into account). See in-depth description in ClickHouse documentation. Value must be greater than 0.
max_memory_usage	google.protobuf.Int64Value Limits the maximum memory usage (in bytes) for processing of a single user's query on a single server. This setting does not take server's free RAM amount or total RAM amount into account. This limitation is enforced for any user's single query on a single server. Minimal value: 0, no limitation is set. Value that is set in the ClickHouse default config file: 10737418240 (10 GB).

input_format_values_interpret_expressions	google.protobuf.BoolValue Enables or disables SQL parser if the fast stream parser cannot parse the data. Enable this setting, if the data that you want to insert into a table contains SQL expressions. For example, the stream parser is unable to parse a value that contains now() expression; therefore an INSERT query for this value will fail and no data will be inserted into a table. With enabled SQL parser, this expression is parsed correctly: the now() expression will be parsed as SQL function, interpreted, and the current date and time will be inserted into the table as a result. This setting has effect only if you use Values format when inserting data. Default value: true (SQL parser is enabled). See in-depth description in ClickHouse documentation.

output_format_json_quote_denormals	google.protobuf.BoolValue Enables special floating-point values (+nan, -nan, +inf and -inf) in JSON output format. Default value: false (special values do not present in output).
low_cardinality_allow_in_native_format	google.protobuf.BoolValue Determines whether to use LowCardinality type in Native format. true (default)-yes, use. false-convert LowCardinality columns to regular columns when doing SELECT, and convert regular columns to LowCardinality when doing INSERT. LowCardinality columns (aka sparse columns) store data in more effective way, compared to regular columns, by using hash tables. If data to insert suits this storage format, ClickHouse will place them into LowCardinality column. If you use a third-party ClickHouse client that can't work with LowCardinality columns, then this client will not be able to correctly interpret the result of the query that asks for data stored in LowCardinality column. Disable this setting to convert LowCardinality column to regular column when creating the result, so such clients will be able to process the result. Official ClickHouse client works with LowCardinality columns out-of-the-box. Default value: true (LowCardinality columns are used in Native format).
empty_result_for_aggregation_by_empty_set	google.protobuf.BoolValue Enables returning of empty result when aggregating without keys (with GROUP BY operation absent) on empty set (e.g., SELECT count(*) FROM table WHERE 0). true-ClickHouse will return an empty result for such queries. false (default)-ClickHouse will return a single-line result consisting of NULL values for aggregation functions, in accordance with SQL standard.

enable_http_compression	google.protobuf.BoolValue Enables or disables data compression in HTTP responses. By default, ClickHouse stores data compressed. When executing a query, its result is uncompressed. Use this setting to command ClickHouse to compress the result when sending it via HTTP. Enable this setting and add the Accept-Encoding: HTTP header in a HTTP request to force compression of HTTP response from ClickHouse. ClickHouse support the following compression methods: gzip, br and deflate. Default value: false (compression is disabled). See in-depth description in ClickHouse documentation.
send_progress_in_http_headers	google.protobuf.BoolValue Enables progress notifications using X-ClickHouse-Progress HTTP header. Default value: false (notifications disabled).
http_headers_progress_interval	google.protobuf.Int64Value Minimum interval between progress notifications with X-ClickHouse-Progress HTTP header, in milliseconds. Value must be greater than 0 (default: 100).
