-----------------------------------
Summary: Create CatalogManager class manages all external catalogs
and temporary meta objects
Key: FLINK-10698
URL: https://issues.apache.org/jira/browse/FLINK-10698
Project: Flink
Issue Type: Sub-task
Components: Table API & SQL
Affects Versions: 1.6.1
Reporter: Xuefu Zhang
Currently {{TableEnvironment}} manages a list of registered external catalogs
as well as in-memory meta objects, and interacts with Calcite schema. It would
be cleaner to delegate all those responsibilities to a dedicate class,
especially when Flink's meta objects are also stored in a catalog.
{{CatalogManager}} is responsible to manage all meta objects, including
external catalogs, temporary meta objects, and Calcite schema.
