> Key: FLINK-22389
> URL: https://issues.apache.org/jira/browse/FLINK-22389
> Project: Flink
> Issue Type: New Feature
> Components: Stateful Functions
> Reporter: Konstantin Knauf
> Assignee: Igal Shilman
> Priority: Major
> Labels: stale-assigned
> Fix For: statefun-3.1.0
>
>
> Stateful Functions always invokes a functions with a batch of messages. Under
> normal operations the batch size=1 (no batching).
> If a function is slow and backpressure arises, the batch size grows, though.
> From an SDK perspective, this batching is not visible. The function is always
> invoked with a single message. This makes it impossible to efficiently
> evaluate the whole batch at once (e.g. with pandas).
> This issue was requested in
> http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Flink-Statefun-Python-Batch-tp43022.html.
