Quanlong Huang updated IMPALA-14089:
------------------------------------
Epic Link: IMPALA-13915
> Support REFRESH on multiple partitions
> --------------------------------------
>
> Key: IMPALA-14089
> URL: https://issues.apache.org/jira/browse/IMPALA-14089
> Project: IMPALA
> Issue Type: New Feature
> Components: Catalog, Frontend
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Major
>
> This is the first step for IMPALA-4105 to help users combine multiple
> partition level REFRESH statements into one:
> {code:sql}
> REFRESH <table>
> PARTITION (...)
> PARTITION (...)
> PARTITION (...)
> ...
> {code}
> This reduces table lock contention in catalogd side and avoids the table
> version being increased multiple times. Also improves the overall performance
> by loading partitions in parallel.
