Task #2221
Story #2067: Refactor the index task generator and processor to improve scalability and performance
Update Task Generation to act only on 'update' events
100%
Description
Related to how hzcast generates map added events for items that have previously been in the map, but evicted. When the item is re-added to distributed map, and 'add' event is called.
Only listen for update events on the system metadata map.
This change mean the IndexTask priority between add/update is no longer useful. Remove/update priority handling logic - no longer can tell and add form and update.

Changing strategy to account for previously evicted items being re-added to system metadata map:
on add event, check the serial version - if greater than 1 - this not a true add, should represent an item re-added to map after eviction.
#3 Updated by Skye Roseboom over 12 years ago
added serial version check to add event handling logic. Add event is ignored if systemMetadata.serialVersion > 1. When the value is greater than 1, this indicates an add event generated when a previously evicted entry is added back into the distributed map.
