----------------------------------
Summary: Enhance order and predictability of reported events in
EventSequence (was: Enhance order and predictability of reported events)
> Enhance order and predictability of reported events in EventSequence
> --------------------------------------------------------------------
>
> Key: IMPALA-13555
> URL: https://issues.apache.org/jira/browse/IMPALA-13555
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Surya Hebbar
> Priority: Major
>
> 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.
