Todd Lipcon resolved KUDU-2867. ------------------------------- Resolution: Fixed Fix Version/s: 1.11.0 > Optimize Timestamp varint decoding > ---------------------------------- > > Key: KUDU-2867 > URL: https://issues.apache.org/jira/browse/KUDU-2867 > Project: Kudu > Issue Type: Improvement > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Priority: Minor > Fix For: 1.11.0 > > > In looking at a profile with some delta reads, I noticed ~11% of CPU going to > GetMemcmpableVarint, much of which is from Timestamp decoding. In practice, > any timestamp from HybridClock will need an 8-byte varint, so we can > fast-path that case. (unfortunately it's too much effort to change the data > format to not use a varint here) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
