This is an attempt at a complete listing of elasticsearch config variables since they’re located all over the elastic.co website.<\/p>\n

The list is not complete, and will start to “rot” as soon as it’s published, but… If you know of some variables that aren’t listed, please let me know.<\/p>\n

Note that static settings must be set in the config file on every machine in the cluster.<\/p>\n

Thread Pool<\/h2>\n

There are several thread pools. Elastic lists the “important” ones as including: generic, index, search, suggest, get, bulk, percolate, snapshot, warmer, refresh, listener. Some settings are documented, and are listed below.<\/p>\n

You can also control the number of processors for a thread pool, which is briefly documented here<\/a>.<\/p>\n\n\n\n\n\n\n
