> FLIP-164: Improve Schema Handling in Catalogs
> ---------------------------------------------
>
> Key: FLINK-21394
> URL: https://issues.apache.org/jira/browse/FLINK-21394
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Timo Walther
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> Schema information is necessary at different locations in the Table API for
> defining tables and/or views. In particular, it is necessary to define the
> schema in a programmatic DDL (FLIP-129) and when converting a DataStream to a
> Table (FLIP-136).
> We need similar APIs in the Catalog interfaces such that catalog
> implementations can define table/views in a unified way.
> This FLIP updates the class hierarchy to achieve the following goals:
> - make it visible whether a schema is resolved or unresolved and when the
> resolution happens
> - offer a unified API for FLIP-129, FLIP-136, and catalogs
> - allow arbitrary data types and expressions in the schema for watermark spec
> or columns
> - have access to other catalogs for declaring a data type or expression via
> CatalogManager
> - cleaned up TableSchema
> - remain backwards compatible in the persisted properties and API
