>                 Key: IMPALA-4967
>                 URL: https://issues.apache.org/jira/browse/IMPALA-4967
>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Catalog
>    Affects Versions: Impala 2.9.0
>            Reporter: Peter Ebert
>
> When running REFRESH table partition (x=1) the metadata distribution contains all partitions,
not just the single partition that was refreshed.  This creates additional load and delays
refreshes.
> To solve metadata updates might have to be serialized (assign unique #, and apply in
order), but this behavior would help the timeliness of data and reduce load on the cluster.
