Todd Lipcon created KUDU-2867: --------------------------------- Summary: 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
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)
