Class BitsetFilterCache

java.lang.Object

org.elasticsearch.index.AbstractIndexComponent

org.elasticsearch.index.cache.bitset.BitsetFilterCache

All Implemented Interfaces:

com.google.common.cache.RemovalListener<Object,com.google.common.cache.Cache<org.apache.lucene.search.Query,BitsetFilterCache.Value>>, Closeable, AutoCloseable, org.apache.lucene.index.LeafReader.CoreClosedListener, IndexComponent

public class BitsetFilterCache
extends AbstractIndexComponent
implements org.apache.lucene.index.LeafReader.CoreClosedListener, com.google.common.cache.RemovalListener<Object,com.google.common.cache.Cache<org.apache.lucene.search.Query,BitsetFilterCache.Value>>, Closeable

This is a cache for BitDocIdSet based filters and is unbounded by size or time.

Use this cache with care, only components that require that a filter is to be materialized as a BitDocIdSet and require that it should always be around should use this cache, otherwise the QueryCache should be used instead.
