Settings

The SQL plugin adds a few settings to the standard OpenSearch cluster settings. Most are dynamic, so you can change the default behavior of the plugin without restarting your cluster.

You can update these settings like any other cluster setting:

PUT _cluster/settings
{
  "transient" : {
    "plugins.sql.enabled" : false
  }
}

Similarly, you can also update the settings by sending the request to the plugin setting endpoint _plugins/_query/setting:

PUT _plugins/_query/settings
{
  "transient" : {
    "plugins.sql.enabled" : false
  }
}

Setting	Default	Description
plugins.sql.enabled	True	Change to false to disable the plugin.
plugins.sql.slowlog	2 seconds	Configure the time limit (in seconds) for slow queries. The plugin logs slow queries as Slow query: elapsed=xxx (ms) in opensearch.log.
plugins.sql.cursor.keep_alive	1 minute	This value configures how long the cursor context is kept open. Cursor contexts are resource heavy, so we recommend a low value.
plugins.query.memory_limit	85%	This setting configures the heap memory usage limit for the circuit breaker of the query engine.
plugins.query.size_limit	200	The setting sets the default size of index that the query engine fetches from OpenSearch.
