Jark Wu updated FLINK-11703:
----------------------------
Description:
In order to support plan test, we need the ability to register a DataStream (or
TableSource) and perform sql query on it.
This issue is aiming to introduce a basic and simple TableEnvironment which
only support {{registerDataStream}} and {{sqlQuery}}.
In the context of FLINK-11067 and FLINK-11068 (convert TableEnvironments and
Tables to interfaces), the introduced {{TableEnvironment}} in
{{table-planner-blink}} is a temporary solution and will be refactored/moved to
a {{BlinkPlanner}}, once FLINK-11067, FLINK-11068 is done.
was:
We need an initial commit to add something like Table, TableEnvironment,
Expressions, ExpressionParser, etc..
They can be copied from flink-table-planner, and add changes to them in the
future when merging Blink features. There are no big differences in these
classes.
