Class EnableMergeScheduler

java.lang.Object

org.apache.lucene.index.MergeScheduler

org.elasticsearch.index.merge.EnableMergeScheduler

All Implemented Interfaces:

Closeable, AutoCloseable

public class EnableMergeScheduler
extends org.apache.lucene.index.MergeScheduler

A wrapper of another MergeScheduler that allows to explicitly enable merge and disable on a thread local basis. The default is to have merges disabled.

This merge scheduler can be used to get around the fact that even though a merge policy can control that no new merges will be created as a result of a segment flush (during indexing operation for example), the merge(org.apache.lucene.index.IndexWriter, org.apache.lucene.index.MergeTrigger, boolean) call will still be called, and can result in stalling indexing.
