Kurt Young commented on FLINK-17793: ------------------------------------ I'm curious about `ResolvedSchema`. What exactly properties being resolved in schema? Another thing is, right now we don't have a dedicated resolving phase in the lifecycle of query processing, where would be the resolving take place? I'm asking because I think we need to have very clear distinguish between `Schema` and `ResolvedSchema`. Every one should now where to use schema and where to use ResolvedSchema, otherwise it will still cause chaos and misuse. > Replace TableSchema with dedicated CatalogSchema > ------------------------------------------------ > > Key: FLINK-17793 > URL: https://issues.apache.org/jira/browse/FLINK-17793 > Project: Flink > Issue Type: Sub-task > Components: Table SQL / API > Reporter: Timo Walther > Assignee: Timo Walther > Priority: Major > > The {{TableSchema}} is used for representing the schema of catalog table and > the schema of a {{Table}} object and operation.
