> Store streaming, updating tables with unique key in queryable state
> -------------------------------------------------------------------
>
> Key: FLINK-6968
> URL: https://issues.apache.org/jira/browse/FLINK-6968
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Reporter: Fabian Hueske
> Assignee: Renjie Liu
> Priority: Major
> Labels: pull-request-available
>
> Streaming tables with unique key are continuously updated. For example
> queries with a non-windowed aggregation generate such tables. Commonly, such
> updating tables are emitted via an upsert table sink to an external datastore
> (k-v store, database) to make it accessible to applications.
> This issue is about adding a feature to store and maintain such a table as
> queryable state in Flink. By storing the table in Flnk's queryable state, we
> do not need an external data store to access the results of the query but can
> query the results directly from Flink.
