-----------------------------
> Enhanced windowing semantics
> ----------------------------
>
> Key: FLINK-1190
> URL: https://issues.apache.org/jira/browse/FLINK-1190
> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 0.8-incubating
> Reporter: Márton Balassi
> Assignee: Gyula Fora
>
> The current windowing, batching options are rather strict: the stream is
> split into smaller units based on either count or time. This model is not
> flexible enough to e.g. describe the following semantics: provide the data
> from the last one second, but provide at most 1000 records.
> The concept is based on IBM InfoSphere Stream's eviction and triggering
> policies, while giving the user the opportunity to define policies.
