Correlation store should version index entries
Reported by Ben Hood | October 10th, 2011 @ 01:29 PM | in 0.9-series (closed)
-
Implement a monotonically increasing version number in the index. A replay will record the latest version number in the diffs store. This will allow us to avoid O(n) syncs between the two stores, since we only need to update the store from a version forwards.
-
Deleted entities will be treated as a tombstone and will get cleared out as part of the clean up process.

(from [d72f0e57a9bd6f7c5822ecd13cb9df8fa30946c2]) [#375] Don't explicitly mark tombstones - infer them from both participants having a negative presence.
This technique eliminates the need for another indexed field, and also helps with cases where something
has become tombstone then is brought back - instead of updating tombstone fields, the relevant indicators
will have changed.
