Tim Armstrong updated IMPALA-7540:
----------------------------------
Issue Type: Improvement (was: Bug)
> Intern common strings in catalog
> --------------------------------
>
> Key: IMPALA-7540
> URL: https://issues.apache.org/jira/browse/IMPALA-7540
> Project: IMPALA
> Issue Type: Improvement
> Affects Versions: Impala 3.1.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Major
>
> Using jxray shows that there are many common duplicate strings in the
> catalog. For example, each table repeats the database name, and metadata like
> the HMS parameter maps reuse a lot of common strings like "EXTERNAL" or
> "transient_lastDdlTime". We should intern these to save memory.
