------------------------------------
Summary: Introduce basic type inference interfaces
Key: FLINK-12924
URL: https://issues.apache.org/jira/browse/FLINK-12924
Project: Flink
Issue Type: Sub-task
Components: Table SQL / API
Reporter: Timo Walther
Assignee: Timo Walther
This issue introduces basic interfaces for performing type inference. It
includes validation of input types and deduction of accumulator or return
types. Argument type inference (i.e. deducing a type for \{{NULL}}) will be
introduced in a later step. The interfaces replace the need for
\{{PlannerExpression}}.
A rough design document can be found here but it needs some update.
Introduction of annotations and basic type extraction will come later:
