Opensearch Settings

Properties

• thread_pool_search_throttled_size (integer): Size for the thread pool. See documentation for exact details. Do note this may have maximum value depending on CPU count - value is automatically lowered if set to higher than maximum value.
• thread_pool_analyze_size (integer): Size for the thread pool. See documentation for exact details. Do note this may have maximum value depending on CPU count - value is automatically lowered if set to higher than maximum value.
• thread_pool_get_size (integer): Size for the thread pool. See documentation for exact details. Do note this may have maximum value depending on CPU count - value is automatically lowered if set to higher than maximum value.
• thread_pool_get_queue_size (integer): Size for the thread pool queue. See documentation for exact details.
• indices_memory_max_index_buffer_size (integer): Absolute value. Default is unbound. Doesn’t work without indices.memory.index_buffer_size. Maximum amount of heap used for query cache, an absolute indices.memory.index_buffer_size maximum hard limit.
• indices_recovery_max_concurrent_file_chunks (integer): Number of file chunks sent in parallel for each recovery. Defaults to 2.
• indices_queries_cache_size (integer): Percentage value. Default is 10%. Maximum amount of heap used for query cache. This is an expert setting. Too low value will decrease query performance and increase performance for other operations; too high value will cause issues with other OpenSearch functionality.
• search_backpressure (object) - schema details
• shard_indexing_pressure (object) - schema details
• knn_memory_circuit_breaker_enabled (boolean): Enable or disable KNN memory circuit breaker. Defaults to true.
• thread_pool_search_size (integer): Size for the thread pool. See documentation for exact details. Do note this may have maximum value depending on CPU count - value is automatically lowered if set to higher than maximum value.
• indices_memory_min_index_buffer_size (integer): Absolute value. Default is 48mb. Doesn’t work without indices.memory.index_buffer_size. Minimum amount of heap used for query cache, an absolute indices.memory.index_buffer_size minimal hard limit.
• indices_recovery_max_bytes_per_sec (integer): Limits total inbound and outbound recovery traffic for each node. Applies to both peer recoveries as well as snapshot recoveries (i.e., restores from a snapshot). Defaults to 40mb
• http_max_initial_line_length (integer): The max length of an HTTP URL, in bytes
• enable_security_audit (boolean)
• thread_pool_write_queue_size (integer): Size for the thread pool queue. See documentation for exact details.
• script_max_compilations_rate (string): Script compilation circuit breaker limits the number of inline script compilations within a period of time. Default is use-context
• search_max_buckets (integer): Maximum number of aggregation buckets allowed in a single response. OpenSearch default value is used when this is not defined.
• reindex_remote_whitelist (array[string]): Whitelisted addresses for reindexing. Changing this value will cause all OpenSearch instances to restart.
• override_main_response_version (boolean): Compatibility mode sets OpenSearch to report its version as 7.10 so clients continue to work. Default is false
• http_max_header_size (integer): The max size of allowed headers, in bytes
• email-sender (object) - schema details
• indices_fielddata_cache_size (integer): Relative amount. Maximum amount of heap memory used for field data cache. This is an expert setting; decreasing the value too much will increase overhead of loading field data; too much memory used for field data cache will decrease amount of heap available for other operations.
• action_destructive_requires_name (boolean)
• plugins_alerting_filter_by_backend_roles (boolean): Enable or disable filtering of alerting by backend roles. Requires Security plugin. Defaults to false
• indices_memory_index_buffer_size (integer): Percentage value. Default is 10%. Total amount of heap used for indexing buffer, before writing segments to disk. This is an expert setting. Too low value will slow down indexing; too high value will increase indexing performance but causes performance issues for query performance.
• thread_pool_force_merge_size (integer): Size for the thread pool. See documentation for exact details. Do note this may have maximum value depending on CPU count - value is automatically lowered if set to higher than maximum value.
• auth_failure_listeners (object) - schema details
• ism-history (object) - schema details
• cluster_routing_allocation_node_concurrent_recoveries (integer): How many concurrent incoming/outgoing shard recoveries (normally replicas) are allowed to happen on a node. Defaults to 2.
• thread_pool_analyze_queue_size (integer): Size for the thread pool queue. See documentation for exact details.
• action_auto_create_index_enabled (boolean): Explicitly allow or block automatic creation of indices. Defaults to true
• http_max_content_length (integer): Maximum content length for HTTP requests to the OpenSearch HTTP API, in bytes.
• thread_pool_write_size (integer): Size for the thread pool. See documentation for exact details. Do note this may have maximum value depending on CPU count - value is automatically lowered if set to higher than maximum value.
• thread_pool_search_queue_size (integer): Size for the thread pool queue. See documentation for exact details.
• knn_memory_circuit_breaker_limit (integer): Maximum amount of memory that can be used for KNN index. Defaults to 50% of the JVM heap size.
• indices_query_bool_max_clause_count (integer): Maximum number of clauses Lucene BooleanQuery can have. The default value (1024) is relatively high, and increasing it may cause performance issues. Investigate other approaches first before increasing this value.
• thread_pool_search_throttled_queue_size (integer): Size for the thread pool queue. See documentation for exact details.
• cluster_max_shards_per_node (integer): Controls the number of shards allowed in the cluster per data node
