> Simplify handling of 'NoMoreSplitsEvent'
> ----------------------------------------
>
> Key: FLINK-19265
> URL: https://issues.apache.org/jira/browse/FLINK-19265
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Common
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> Split assignment events are treated specially by the source API. Users do not
> create them directly but call methods on the contexts to assign splits.
> The {{NoMoreSplitsEvent}} is in contrast to that a custom user event and
> needs to be handled like a custom event, when sent by enumerators and
> received by the readers.
> That seems a bit confusing and inconsistent, given that NoMoreSplits is
> essential for all bounded stream use cases and is on the same level as the
> {{AddSplitEvent}}.
> I suggest that we treat "no more splits" similarly, by having either a custom
> method or a custom "SplitAssignment" on the context and reader.
> [~jqin] Curious what would be your take on this.
