How to use

DirectoryImplementor

in

org.infinispan.lucene.impl

/**
* @param metadataCache the cache to be used for all smaller metadata: prefer replication over distribution, avoid eviction
* @param chunksCache the cache to use for the space consuming segments: prefer distribution, enable eviction if needed
* @param distLocksCache the cache to use for locks, to avoid more than one process to write to the index
* @param indexName the unique index name, useful to store multiple indexes in the same caches
* @param lf the LockFactory to be used by IndexWriters. @see org.infinispan.lucene.locking
* @param chunkSize segments are fragmented in chunkSize bytes; larger values are more efficient for searching but less for distribution and network replication
* @param readLocker @see org.infinispan.lucene.readlocks for some implementations; you might be able to provide more efficient implementations by controlling the IndexReader's lifecycle.
* @param fileListUpdatedAsync When true, the writes to the list of currently existing files in the Directory will use the putAsync method rather than put.
* @param deleteExecutor The Executor to run file deletes in the background
* @param affinitySegmentId A hint interpreted by the consistent hashing function to force locality with a specific segment identifier
