[jira] [Created] (OAK-1465) performance degradation with growing index size on Oak-Mongo

Stefan Egli created OAK-1465:
--------------------------------

             Summary: performance degradation with growing index size on Oak-Mongo
                 Key: OAK-1465
                 URL: https://issues.apache.org/jira/browse/OAK-1465
             Project: Jackrabbit Oak
          Issue Type: Bug
    Affects Versions: 0.17.1
            Reporter: Stefan Egli


Tested with an oak-snapshot of Monday Feb 23, 10AM EST.

Noticed that when the amount of nodes indexed - eg wrt a particular property - the adding of nodes becomes slower and slower.

Will attach a oak-run benchmark to underline this. Basically the scenario where this occurred was:
 * have a number of "level 1" nodes (eg 100)
 * under those "level 1" nodes, add a growing list of children, each with a property that is indexed (ie that index is actually growing and is probably causing the slowdown).
