Tomek Rękawek commented on OAK-4124:
------------------------------------
We are doing this in the current 1.4/trunk, but it resulted in performance
issues during some cache-intensive operations (installing the content and
indexing).
> Persistent cache: consider using callstack blocking

> Key: OAK-4124

> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: cache

> Attachments: OAK-4124.patch

>
> In the current implementation of the asynchronous add operation in
> persistence cache, data are added to a queue and if the queue is full, the
> oldest entries are removed (see OAK-2761).
> It may deteriorate the system performance in some cases (OAK-4123). Let's
> consider a different approach, in which we block the caller thread in case
> the queue is full.
