Ziyun Fu reassigned KAFKA-21202:
--------------------------------
Assignee: Ziyun Fu (was: Chia-Ping Tsai)
> 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: Ziyun Fu
> Priority: Minor
>
> 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.
