Thanks for looking. > [0.98] Save object creation for scanning with block encodings > ------------------------------------------------------------- > > Key: HBASE-14628 > URL: https://issues.apache.org/jira/browse/HBASE-14628 > Project: HBase > Issue Type: Bug > Reporter: Lars Hofhansl > Assignee: Lars Hofhansl > Fix For: 0.98.16 > > Attachments: 14628-0.98-v2.txt, 14628-0.98.txt > > > I noticed that (at least in 0.98 - master is entirely different) we create > ByteBuffer just to create a byte[], which is then used to create a KeyValue. > We can save the creation of the ByteBuffer and hence save allocating an extra > object for each KV we find by creating the byte[] directly. > In a Phoenix count\(*) query that saved from 10% of runtime. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
