> Expose replica selection option that provides better affinity for remote scans
> ------------------------------------------------------------------------------

> Key: KUDU-3248
> URL: https://issues.apache.org/jira/browse/KUDU-3248
> Project: Kudu
> Issue Type: Improvement
> Components: client
> Reporter: David Rorke
> Assignee: Grant Henke
> Priority: Major
> Fix For: 1.15.0
>
>
> Kudu clients like Impala that use the CLOSEST_REPLICA selection option can
> suffer from bad tserver buffer cache warmup/locality during remote scans due
> to lack of tserver affinity as described in IMPALA-10481.
> The Kudu client should expose a replica selection option that provides better
> affinity when doing remote scans. The comments in IMPALA-10481 suggest a
> new LOCAL_OR_LEADER option that would select a local replica if one exists,
> otherwise fallback to the leader.
