[jira] [Created] (KAFKA-21202) listTransactionStates doesn't need to hold the lock so long

Chia-Ping Tsai created KAFKA-21202:
--------------------------------------

             Summary: listTransactionStates doesn't need to hold the lock so long
                 Key: KAFKA-21202
                 URL: https://issues.apache.org/jira/browse/KAFKA-21202
             Project: Kafka
          Issue Type: Improvement
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


We could create a snapshot of `transactionMetadataCache` and then release the lock to complete the subsequent filter.  The per-partition maps are {{{}ConcurrentHashMap{}}}, so iterating them outside the lock is safe.
