Subject [jira] [Created] (OAK-4123) Persistent cache: control the add data concurrency
Date Mon, 14 Mar 2016 09:17:33 GMT
Tomek Rękawek created OAK-4123:

             Summary: Persistent cache: control the add data concurrency
                 Key: OAK-4123
                 URL: https://issues.apache.org/jira/browse/OAK-4123
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: cache
            Reporter: Tomek Rękawek
             Fix For: 1.4.1

During operations that creates and reads a large number of nodes (eg. indexing content) it
may happen that there's more items in the asynchronous queue (introduced in OAK-2761) than
the queue consumer can handle. As a result, the queue is purged and items are not saved in
the cache, which makes the overall performance worse.

An easy fix is to add a property that allows to switch between async/sync mode. By default,
it should be synchronous.
