Subject [jira] [Updated] (FLINK-11703) Introduce TableEnvironment and support registerDataStream and sqlQuery
Date Thu, 07 Mar 2019 09:50:00 GMT

     [ https://issues.apache.org/jira/browse/FLINK-11703?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
