Lars Michele updated JCR-3449:
------------------------------
Status: Patch Available (was: Open)
One small thing about this patch: in the moment, if one thread closes the
session, all other threads will throw a "Session closed" RepositoryException,
but I think this situation has to be handled by the user.
> Improved performance for concurrent read-only access
> ----------------------------------------------------

> Key: JCR-3449
> URL: https://issues.apache.org/jira/browse/JCR-3449
> Project: Jackrabbit Content Repository
> Issue Type: Improvement
> Components: jackrabbit-core
> Affects Versions: 2.4.3, 2.2.13
> Reporter: Lars Michele
> Priority: Minor
> Attachments: jackrabbit-concurrent-read.patch
>
>
> This patch relates to JCR-890. The current implementation allows to share a
> session across multiple threads reading, but the locking mechanism used makes
> this use-case slow. The attached patch uses a ReentrantReadWriteLock for
> accessing session internals, which allows concurrent reads be executed
> concurrently. The only drawback is, that for the "autofix" feature to work as
> before one has to instantiate a thread on such cases, because it cannot be
> executed in the read-scope of a the session facing such problems.
