----------------------------------
Summary: Property index stored locally
Key: OAK-4233
URL: https://issues.apache.org/jira/browse/OAK-4233
Project: Jackrabbit Oak
Issue Type: Improvement
Components: documentmk, query
Reporter: Tomek Rękawek
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.
