> Slow local cache built-up time
> ------------------------------
>
> Key: JCR-3734
> URL: https://issues.apache.org/jira/browse/JCR-3734
> Project: Jackrabbit Content Repository
> Issue Type: Sub-task
> Components: jackrabbit-core
> Affects Versions: 2.7.4
> Reporter: Shashank Gupta
> Assignee: Dominique Pfister
> Fix For: 2.7.5
>
>
> urrently with the S3 connector, it appears that the startup will attempt to
> scan the local datastore on local disk and slow down the startup process.
> Attached are the thread dumps, profiling results and logs for further
> investigation. It will be great if the startup can avoid such a scan or this
> can be optimised further.
> Customer's business impact -
> " It's going to be a scalability issue as the cache grows. Currently we only
> have 64GB or less, which takes 8+ minutes, if we double or quadruple the
> cache, application startup is going to be far too slow for us. We might be
> able to take advantage of SSD attached disk rather than HDD attached disk,
> but we need to evaluate this option further and we want a better fix than
> simply throwing faster storage at it.
> Ideally we want repository to come online as fast as possible and complete
> any cache size counting activities in the background, or have repository
> retain a memory of it's cache status from when it was last running so that at
> startup it picks up it's state and doesn't need to scan the whole cache."
