Subject [jira] [Created] (OAK-4124) Persistent cache: consider using callstack blocking
Date Mon, 14 Mar 2016 09:22:33 GMT
Tomek Rękawek created OAK-4124:

             Summary: Persistent cache: consider using callstack blocking
                 Key: OAK-4124
                 URL: https://issues.apache.org/jira/browse/OAK-4124
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: cache
            Reporter: Tomek Rękawek
             Fix For: 1.6

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.
