Lucene.Net.Index.ConcurrentMergeScheduler Class Reference

A MergeScheduler that runs each merge using a separate thread, up until a maximum number of threads (MaxThreadCount) at which when a merge is needed, the thread(s) that are updating the index will pause until one or more merges completes. This is a simple way to use concurrency in the indexing process without having to create and manage application level threads. More...

Detailed Description

A MergeScheduler that runs each merge using a separate thread, up until a maximum number of threads (MaxThreadCount) at which when a merge is needed, the thread(s) that are updating the index will pause until one or more merges completes. This is a simple way to use concurrency in the indexing process without having to create and manage application level threads.
