Surya Hebbar updated IMPALA-13555:
----------------------------------
Description:
In some cases, when the instances responsible for generating 'labels' map have
missing events, it is functionally not possible to extract the perfect order.
The current event aggregation mechanism, fails to provide an absolute method to
align and order the missing events' timestamp in many edge cases.
It would be great to enhance EventSequence's constructor and the collection
mechanism along with a cleanup and performance boost provided by switching to a
completed version of profile V2.
