Catalog

C++ Paimon provides a Catalog abstraction to manage the table of contents and metadata. The Catalog abstraction provides a series of ways to help you better integrate with computing engines. We always recommend that you use Catalog to access the Paimon table.

Filesystem Catalog

C++ Paimon catalog currently support one types of metastores filesystem metastore (default), which stores both metadata and table files in filesystems.

Note

Current C++ Paimon only supports filesystem catalog. In the future, we will support REST catalog. By using the Paimon REST catalog, changes to the catalog will be directly stored in a remote catalog server which exposed through REST API. See Java Paimon REST Catalog.
