== Indices

The indices module controls index-related settings that are globally managed
for all indices, rather than being configurable at a per-index level.

Available settings include:

<<circuit-breaker,Circuit breaker>>::

    Circuit breakers set limits on memory usage to avoid out of memory exceptions.

<<modules-fielddata,Fielddata cache>>::

    Set limits on the amount of heap used by the in-memory fielddata cache.

<<query-cache,Node query cache>>::

    Configure the amount of heap used to cache queries results.

<<indexing-buffer,Indexing buffer>>::

    Control the size of the buffer allocated to the indexing process.

<<shard-request-cache,Shard request cache>>::

    Control the behaviour of the shard-level request cache.

<<recovery,Recovery>>::

    Control the resource limits on the shard recovery process.

<<search-settings,Search Settings>>::

    Control global search settings.

Rename caches. In order to be more consistent with what they do, the query cache has been renamed to request cache and the filter cache has been renamed to query cache. A known issue is that package/logger names do no longer match settings names, please speak up if you think this is an issue. Here are the settings for which I kept backward compatibility. Note that they are a bit different from what was discussed on #11569 but putting `cache` before the name of what is cached has the benefit of making these settings consistent with the fielddata cache whose size is configured by `indices.fielddata.cache.size`: * index.cache.query.enable -> index.requests.cache.enable * indices.cache.query.size -> indices.requests.cache.size * indices.cache.filter.size -> indices.queries.cache.size Close #11569 2015-06-26 10:31:38 -04:00			`<<query-cache,Node query cache>>::`
