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

== 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 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.
|
|
|
|
<<indices-ttl,TTL interval>>::
|
|
|
|
Control how expired documents are removed.
