Adrien Grand	db9af54ec0	Remove `_timestamp` and `_ttl` on 5.x indices. #18980 ... This removes the ability to use `_timestamp` and `_ttl` on indices created on or after 5.0. Closes #18280	2016-06-22 08:35:54 +02:00
Daniel Mitterdorfer	52b2016447	Limit request size on transport level ... With this commit we limit the size of all in-flight requests on transport level. The size is guarded by a circuit breaker and is based on the content size of each request. By default we use 100% of available heap meaning that the parent circuit breaker will limit the maximum available size. This value can be changed by adjusting the setting network.breaker.inflight_requests.limit Relates #16011	2016-04-13 09:54:59 +02:00
Adrien Grand	0eb1a816c8	Allow the query cache to be disabled. #16268 ... This replaces the internal `index.queries.cache.type` setting with a new `index.queries.cache.enabled` setting, which is documented. Closes #15802	2016-04-11 18:06:16 +02:00

Simon Willnauer	f5e4cd4616	Remove recovery threadpools and throttle outgoing recoveries on the master ... Today we throttle recoveries only for incoming recoveries. Nodes that have a lot of primaries can get overloaded due to too many recoveries. To still keep that at bay we limit the number of threads that are sending files to the target to overcome this problem. The right solution here is to also throttle the outgoing recoveries that are today unbounded on the master and don't start the recovery until we have enough resources on both source and target nodes. The concurrency aspects of the recovery source also added a lot of complexity and additional threadpools that are hard to configure. This commit removes the concurrent streamns notion completely and sends files in the thread that drives the recovery simplifying the recovery code considerably. Outgoing recoveries are not throttled on the master via a allocation decider.	2015-12-22 14:59:43 +01:00

Adrien Grand	38f5cc236a	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	2015-06-29 10:15:27 +02:00
