    Description

      In LocalCatalog there is no need for every coordinator to have the full list of tables of every database. But, getCatalogMetrics ends up iterating over every DB and fetching these lists in order to provide a count. The count isn't particularly relevant – if someone wants to keep track of the size of their catalog they are better off looking at that metric from catalogd. We should remove these catalog metrics.
