Package com.apple.foundationdb.record.lucene.codec

Class LuceneOptimizedCodec

java.lang.Object
org.apache.lucene.codecs.Codec
com.apple.foundationdb.record.lucene.codec.LuceneOptimizedCodec
All Implemented Interfaces:
org.apache.lucene.util.NamedSPILoader.NamedSPI
@AutoService(org.apache.lucene.codecs.Codec.class) public class LuceneOptimizedCodec extends org.apache.lucene.codecs.Codec
Codec with a few optimizations for speeding up compound files sitting on FoundationDB. Optimizations: - .cfe file references are not stored - .cfe file data is serialized as entries on the current compound file reference (.cfs) - .si file references are not stored - .si file data is serialized as segmentInfo on the current compound file reference (.cfs) - .si diagnostic information is not stored - Removed checksum validation on Compound File Reader Forwards/backwards compatibility is not supported during transition from the Lucene87Codec to this implementation unfortunately. Indexes need to rebuilt before handling search requests.
