    Description

      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.
