----------------------------------------
Summary: JournalImpl::checkKnownRecordID can save RTT on append
executor
Key: ARTEMIS-3290
URL: https://issues.apache.org/jira/browse/ARTEMIS-3290
Project: ActiveMQ Artemis
Issue Type: Improvement
Reporter: Francesco Nigro
Assignee: Francesco Nigro
{\{JournalImpl::checkKnownRecordID}}'s slow path, is performing a RTT on the
journal `appendExecutor` to check for record existence, if the journal is still
processing some record.
Considered that \{{checkKnownRecordID}} is always happening before a real
append, that's again being called on the same executor, probably worth inlining
the \{{checkKnownRecordID}} slow path into the subsequent append happening on
the append executor, saving 1 RTT and improving append latency under heavy load.
