[jira] [Created] (QPID-3736) [Java Broker] Update BDB store to v5
and utilise explicit log flush for significant performance improvement
[Java Broker] Update BDB store to v5 and utilise explicit log flush for significant performance improvement
-----------------------------------------------------------------------------------------------------------
Key: QPID-3736
URL: https://issues.apache.org/jira/browse/QPID-3736
Project: Qpid
Issue Type: Improvement
Reporter: Rob Godfrey
Assignee: Rob Godfrey
BDB v5 adds a new method to Environment to allow for the flushing of logs to disk (synchronously if desired) without having to run a full checkpoint. This seems to directly address our use case of BDB.
Upgrading BDB and making use of this feature shows significant performance benefits, especially where there are a low number of concurrent connections.
For a single producer/consumer transactional case, I have observed a performance increase of 56%; for 2 producers/consumers 50%...
