Examples of EnableMergeScheduler

org.elasticsearch.index.merge.EnableMergeScheduler

A wrapper of another {@link org.apache.lucene.index.MergeScheduler} that allowsto 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 {@link #merge(org.apache.lucene.index.IndexWriter,org.apache.lucene.index.MergeTrigger,boolean)}call will still be called, and can result in stalling indexing.


    public final MergeScheduler newMergeScheduler() {
        MergeScheduler scheduler = buildMergeScheduler();
        // an internal settings, that would allow us to disable this behavior if really needed
        if (indexSettings.getAsBoolean(FORCE_ASYNC_MERGE, true)) {
            scheduler = new EnableMergeScheduler(scheduler);
        }
        return scheduler;
    }
