Timo Walther created FLINK-14983: ------------------------------------ Summary: Add interfaces for input type inference Key: FLINK-14983 URL: https://issues.apache.org/jira/browse/FLINK-14983 Project: Flink Issue Type: Sub-task Components: Table SQL / API Reporter: Timo Walther Assignee: Timo Walther
The [design document|https://docs.google.com/document/d/1RM_-XvD25AldUOl7xRSvA3sascWBa1-Jze3i5mvb7WU/edit#] around {{TypeInference}} already mentioned an {{InputTypesInference}} that enables the derivation of missing or incomplete input signatures. The Calcite equivalent is called {{SqlOperandTypeInference}}. For FLIP-65, we will need to implement those interfaces as the planner needs infer the {{DataType}}s out of logical types that come from the logical query. This is also beneficial to support the {{NULL}} literal in the future. -- This message was sent by Atlassian Jira (v8.3.4#803005)
