nicktelford opened a new pull request, #14852:
URL: https://github.com/apache/kafka/pull/14852

   When opening RocksDB, we were checking for an error in 
`RocksDBTimestampedStore` to detect if the `keyValueWithTimestamp` CF is 
missing.
   
   The `openRocksDB` method now supports any number of column families, not 
just the extra one used by `RocksDBTimestampedStore`. We now check for the 
existing column families _before_ opening the database, which allows us to 
create any missing column families.
   
   Supporting automatic creation of any number of missing column families is a 
pre-requisite for KIP-892: Transactional StateStores.
