      Description

      The catalog metadata can become large and lead to excessive network traffic due to dissemination via the statestore. The --compact_catalog_topic flag was introduced to mitigate this issue by compressing the catalog topic entries to reduce their serialized size.
      This saves network bandwidth at the cost of a small quantity of CPU time.

      To improve the out-of-the box experience of users we should enable this flag by default.
