Task #1201
closedTask #1196: Measurements table
Measurements table cleanup
Description
Implement a mechanism to delete outdated entries from the measurements table.
Updated by Junxiao Shi over 10 years ago
20140214 conference call proposes a different approach:
each measurements entry contains a timer to delete itself.
This avoids enumerating all table entries to find those needs deleted.
Scheduler
has O(log n) time complexity for event insertion, where n is the number of scheduled events.
Typically, measurements entry shall not be deleted until after PIT entry is deleted.
Therefore, the number of scheduled events should be close to the number of PIT entries.
