Class ExecutorMergeScheduler

java.lang.Object
  org.apache.lucene.index.MergeScheduler
      org.apache.lucene.index.ExecutorMergeScheduler

public class ExecutorMergeScheduler
extends MergeScheduler

The executor merge scheduler is similar to Lucene ConcurrentMergeScheduler but instead of spawning threads it uses Compass ExecutorManager in order to execute the merges.

Since the executor manager is a thread pool, there is no need to have the running threads continue to ask the index writer for more merges. Instead, it simple reexecute another possible merge with the executor manager.
