-------------------------------
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)
