+## Catalog Store
+
+Catalog Store is used to store the configuration of catalogs. When using
Catalog Store, the configurations
+of catalogs created in the session will be persisted in the corresponding
external system of Catalog Store.
+Even if the session is reconstructed, previously created catalogs can still be
retrieved from Catalog Store.
+
+### Configure Catalog Store
+Users can configure the Catalog Store in different ways, one is to use the
Table API, and another is to use YAML configuration.

FileCatalogStore("file://path/to/catalog/store/");
+
+// set up the catalog store

Review Comment:
Can we put them into different code blocks? It's a bit strange to put them
together
