-----------------------------
Summary: Introduce comment for Catalog (was: Introduce comment support for
Catalog)
> Introduce comment for Catalog
> -----------------------------
>
> Key: FLINK-34918
> URL: https://issues.apache.org/jira/browse/FLINK-34918
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / API
> Affects Versions: 1.20.0
> Reporter: Yubin Li
> Assignee: Yubin Li
> Priority: Major
>
> We propose to introduce `getComment()` method in `CatalogDescriptor`, and the
> reasons are as follows.
> 1. For the sake of design consistency, follow the design of FLIP-295 [1]
> which introduced `CatalogStore` component, `CatalogDescriptor` includes names
> and attributes, both of which are used to describe the catalog, and `comment`
> can be added smoothly.
> 2. Extending the existing class rather than add new method to the existing
> interface, Especially, the `Catalog` interface, as a core interface, is used
> by a series of important components such as `CatalogFactory`,
> `CatalogManager` and `FactoryUtil`, and is implemented by a large number of
> connectors such as JDBC, Paimon, and Hive. Adding methods to it will greatly
> increase the implementation complexity, and more importantly, increase the
> cost of iteration, maintenance, and verification.
