> Spooling pending messages in the large transaction to the disk
> --------------------------------------------------------------
>
> Key: AMQ-4311
> URL: https://issues.apache.org/jira/browse/AMQ-4311
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Broker, Message Store
> Affects Versions: 5.x
> Reporter: SuoNayi
> Fix For: 5.9.0
>
>
> Currently MemoryTransactionStore is used to hold pending messages in a
> transaction.
> More pending messages in a transaction more memory is consumed.
> Because the message size of pending messages is not counted in usage limit
> before they are committed so PFC wont block producers as well and large
> transaction will cause broker throws OOM at last.
> Spooling pending messages in the transaction to the disk is one of solution.
