> Merge InputTypeStrategy and InputTypeValidator

> Key: FLINK-15149
> URL: https://issues.apache.org/jira/browse/FLINK-15149
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / API
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
> Labels: pull-request-available
>
> Due to the design of Calcite, even operand checkers that were originally used
> for "checking" can infer and modify call arguments nowadays. This conflicts
> with our original design of separating validation and input type inference.
> Therefore, we propose to merge those two concepts in Flink into one
> `InputTypeStrategy` that is responsible for both inferring/enriching and
> validation.
