Gary Tully updated AMQ-5603: ---------------------------- Issue Type: Improvement (was: New Feature) > Consider preallocation of journal files in batch increments > ----------------------------------------------------------- > > Key: AMQ-5603 > URL: https://issues.apache.org/jira/browse/AMQ-5603 > Project: ActiveMQ > Issue Type: Improvement > Components: Message Store > Reporter: Christian Posta > Priority: Minor > Labels: kahaDB, perfomance > > Right now (as of ActiveMQ 5.12 release) we preallocate journal files, but the > only scope is for entire journal file. The [potential] issue with that is if > user configures large journal file sizes, we can end up stalling writes > during log rotation because of the allocation process. There are two ways to > do the allocation, configurable to do it in userspace, or defer to kernel > space, but nevertheless it would be good to avoid this issue altogether by > preallocating in small batch sizes regardless of the journal max file size. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
