-----------------------------------
Summary: Intern common strings in catalog
Key: IMPALA-7540
URL: https://issues.apache.org/jira/browse/IMPALA-7540
Project: IMPALA
Issue Type: Bug
Affects Versions: Impala 3.1.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
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.
