binlijin commented on HBASE-16703: ---------------------------------- 0.98 is the same as master and branch 1. I think the INITIAL_KEY_BUFFER_SIZE(512) is too big, because i think not too much keys will be that long. > Explore object pooling of SeekerState > ------------------------------------- > > Key: HBASE-16703 > URL: https://issues.apache.org/jira/browse/HBASE-16703 > Project: HBase > Issue Type: Task > Reporter: Andrew Purtell > > In read workloads 35% of the allocation pressure produced by servicing RPC > requests, when block encoding is enabled, comes from > BufferedDataBlockEncoder$SeekerState.<init>, where we allocate two byte > arrays of INITIAL_KEY_BUFFER_SIZE in length. There's an opportunity for > object pooling of SeekerState here. Subsequent code checks if those byte > arrays are sized sufficiently to handle incoming data to copy. The arrays > will be resized if needed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
