[jira] [Created] (OAK-4233) Property index stored locally

Tomek Rękawek created OAK-4233:
----------------------------------

             Summary: Property index stored locally
                 Key: OAK-4233
                 URL: https://issues.apache.org/jira/browse/OAK-4233

          Issue Type: Improvement
          Components: documentmk, query

            Priority: Minor
             Fix For: 1.6


When running Oak in a cluster, each write operation is expensive. After performing some stress-tests with a geo-distributed Mongo cluster, we've found out that updating property indexes is a large part of the overall traffic. Let's try to create a new property-local index, that will save the indexed data locally, without sharing it.

Assumptions:
-there's a new {{property-local}} index type for which the data are saved in the local SegmentNodeStore instance created specifically for this purpose,
-local changes are indexed using a new editor, based on the {{PropertyIndexEditor}},
-remote changes are extracted from the JournalEntries fetched in the background read operation and indexed as well,
-the new index type won't support uniqueness restriction.
