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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
