Gautam Worah deleted comment on LUCENE-10394: --------------------------------------- was (Author: gworah): I'll try to work on this soon. Looking into the ByteBuffer API in the meantime. > Explore moving ByteBuffer(sData|Index)Input to absolute bulk gets > ----------------------------------------------------------------- > > Key: LUCENE-10394 > URL: https://issues.apache.org/jira/browse/LUCENE-10394 > Project: Lucene - Core > Issue Type: Task > Reporter: Adrien Grand > Priority: Minor > > With the move to Java 17, we now have access to absolute bulk gets on > ByteBuffers: > https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/nio/ByteBuffer.html#get(int,byte%5B%5D,int,int). > We should look into whether this helps with our more random-access workloads > like binary doc values, conjunctive queries and building HNSW graphs. > ByteBuffersDataInput already tries to access the underlying buffers in a > random-access fashion and works around the lack of absolute bulk gets by > doing {{ByteBuffer#duplicate()}}. It looks like a low hanging fruit to stop > duplicating the buffer and just do an absolute bulk get instead. > ByteBuffersIndexInput would require a bit more work since it's performing > relative reads whenever possible. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
