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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
