> Improve batching logic of events
> --------------------------------
>
> Key: IMPALA-10949
> URL: https://issues.apache.org/jira/browse/IMPALA-10949
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Reporter: Vihang Karajgaonkar
> Assignee: Sai Hemanth Gantasala
> Priority: Major
>
> This is a followup based on the review comment
> https://gerrit.cloudera.org/#/c/17848/2/fe/src/main/java/org/apache/impala/catalog/events/MetastoreEvents.java@1641
> Current approach of batching batches together the events from a single
> operation so that self-event check is done per-batch. However, it looks like
> there is a considerable scope of improving the batching logic by clubbing
> together accross the various sources of the events on a table when
> IMPALA-10926 is merged. After IMPALA-10926 each table will track the
> last_synced_event and then the events processor can simply ignore a event
> which <= the last_synced_event. This simplification of self-events logic will
> enable easier batching for all the events of a type on a table.
