> Remove db/table count metrics from impalad in LocalCatalog mode
> ---------------------------------------------------------------
>
> Key: IMPALA-8675
> URL: https://issues.apache.org/jira/browse/IMPALA-8675
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Reporter: Todd Lipcon
> Assignee: Quanlong Huang
> Priority: Minor
> Labels: catalog-v2
> Fix For: Impala 4.4.0
>
>
> In LocalCatalog there is no need for every coordinator to have the full list
> of tables of every database. But, getCatalogMetrics ends up iterating over
> every DB and fetching these lists in order to provide a count. The count
> isn't particularly relevant -- if someone wants to keep track of the size of
> their catalog they are better off looking at that metric from catalogd. We
> should remove these catalog metrics.
