Summary: Reduce reflection usage in Filter deserialization Key: HBASE-27276 URL: https://issues.apache.org/jira/browse/HBASE-27276 Project: HBase Issue Type: Improvement Reporter: Bryan Beaudreault Attachments: async-prof-pid-9037-cpu-1.html Running hbase 2.4.x, I recently profiled one of our clusters which does a very high volume of random reads. An astonishing 12% of CPU time was just spent deserializing in ProtobufUtil.toFilter. One immediate thought would be to cache String -> Class mappings. Currently Class.forName shows up multiple times (6 in my example) in the profile, each time taking over 1%. I think this is partially due to using FilterList in this example. -- This message was sent by Atlassian Jira (v8.20.10#820010)
