-------------------------------------
Assignee: Rui Wang
> [SQL] Support LIMIT
> -------------------
>
> Key: BEAM-4194
> URL: https://issues.apache.org/jira/browse/BEAM-4194
> Project: Beam
> Issue Type: New Feature
> Components: dsl-sql
> Reporter: Anton Kedin
> Assignee: Rui Wang
> Priority: Major
>
> We need to support queries with "LIMIT xxx".
> Problem is that we don't know when aggregates will trigger, they can
> potentially accumulate values in global window and never trigger.
> If we have some trigger syntax (BEAM-4193), then the use case becomes similar
> to what we have at the moment, where the user defines the trigger upstream
> for all inputs. In this case LIMIT probably can be implemented as
> sample.any(5) with trigger at count.
