TableEnvironment
dawidwys opened a new pull request #8984: [FLINK-13088][table-api] Support lazy query transformation & execution on TableEnvironment
URL: https://github.com/apache/flink/pull/8984
## What is the purpose of the change
In the long run we want to have a single self-contained unified `TableEnvironment` equivalent to `ExecutionEnvironment` & `StreamExecutionEnvironment` with `execute` method. Moreover Blink planner translates queries lazily when the `execute` method is called on `TableEnvironment` This PR enables creating an instance of the unified TableEnvironment. It also implements the lazy translation schema.
