> FLINK-12924 introduced new interfaces for performing type inference. We need a set of predefined type validators, strategies, and transformations implemented with the new interfaces in order to represent the old type checking logic. Those interfaces can be inspired by Calcite's {{org.apache.calcite.sql.type.ReturnTypes}}, {{org.apache.calcite.sql.type.OperandTypes}}, and {{org.apache.calcite.sql.type.SqlTypeTransforms}}.
