---------------------------------
Assignee: Peter Vary
> Better usability for SHOW COMPACTIONS
> -------------------------------------
>
> Key: HIVE-21443
> URL: https://issues.apache.org/jira/browse/HIVE-21443
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Reporter: Todd Lipcon
> Assignee: Peter Vary
> Priority: Major
>
> Currently on a test cluster the output of 'SHOW COMPACTIONS' has 117k rows.
> This makes it basically useless to work with.
> For better usability, we should support syntax like 'SHOW COMPACTIONS IN
> <database>' or maybe 'SHOW COMPACTIONS ON <table>' (particular syntax to be
> chosen for consistency with other operations I suppose).
> Alternatively (or maybe in addition) it seems like it would be nice to expose
> the same data in a queryable table (eg in information_schema or a system
> namespace) so that I could do things like: SELECT dbname, state, count(*)
> from compactions group by 1,2;
