> Add support for embedded streaming SQL (projection, filter, union)
> ------------------------------------------------------------------
>
> Key: FLINK-3727
> URL: https://issues.apache.org/jira/browse/FLINK-3727
> Project: Flink
> Issue Type: Sub-task
> Components: Table API
> Affects Versions: 1.1.0
> Reporter: Vasia Kalavri
> Assignee: Vasia Kalavri
>
> Similar to the support for SQL embedded in batch Table API programs, this
> issue tracks the support for SQL embedded in stream Table API programs. The
> only currently supported operations on streaming Tables are projection,
> filtering, and union.
