[jira] [Created] (ARTEMIS-1570) SharedNothingBackup does not
replicate all journal from live
shoukun huai created ARTEMIS-1570:
-------------------------------------
Summary: SharedNothingBackup does not replicate all journal from live
Key: ARTEMIS-1570
URL: https://issues.apache.org/jira/browse/ARTEMIS-1570
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker
Affects Versions: 2.4.0
Environment: i'm running unit test on windows.
Reporter: shoukun huai
Priority: Critical
Attachments: SharedNothingReplicationTest.java
I try to test replication when live is in heavy IO load.
Attached is my junit test.
The test use a slow message persister to simulate live is busy on IO, so JournalImpl's `appendExecutor` is busy.
After start live server, send 5 messages each with a property `delay` of 5000 ms, then start the backup server, wait until it is replicated. Then send more messages without delay.
Stop live and backup after all message sent, then check message journal.
Backup will miss 2 message/journal entry.
