>
> 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.
