                 Key: FLINK-13015
                 URL: https://issues.apache.org/jira/browse/FLINK-13015
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / API
    Affects Versions: 1.9.0
            Reporter: Dawid Wysakowicz

The goal of this task is to implement :

InputTypeValidator:
* by type root

TypeStrategies:
* cascade
* explicit

TypeTransformations:

This set of classes will enable porting AND/OR/NOT/IS_TRUE/IS_FALSE/IS_NOT_TRUE/IS_NOT_FALSE to new type inference stack.
