> Key: ZOOKEEPER-323
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-323
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Reporter: Benjamin Reed
>
> in some benchmarks i noticed that you can get much higher throughput using
> preallocated files rather than doing the grow-by-padding approach that we
> use. we should recycle log files that are no longer needed. this should give
> us a performance boost. it will also make the purgelog utility unnecessary.
> we should have a policy that we only keep X snapshots and associated logs and
> reuse older log files (and probably delete the older snapshots as well since
> the snapshot would be useless without the corresponding log file.)
