org.apache.iceberg.nessie

Class NessieCatalog

java.lang.Object

org.apache.iceberg.BaseMetastoreCatalog

org.apache.iceberg.nessie.NessieCatalog

All Implemented Interfaces:

java.lang.AutoCloseable, org.apache.hadoop.conf.Configurable, org.apache.iceberg.catalog.Catalog, org.apache.iceberg.catalog.SupportsNamespaces

public class NessieCatalog
extends org.apache.iceberg.BaseMetastoreCatalog
implements java.lang.AutoCloseable, org.apache.iceberg.catalog.SupportsNamespaces, org.apache.hadoop.conf.Configurable

Nessie implementation of Iceberg Catalog.

A note on namespaces: Nessie namespaces are implicit and do not need to be explicitly created or deleted. The create and delete namespace methods are no-ops for the NessieCatalog. One can still list namespaces that have objects stored in them to assist with namespace-centric catalog exploration.
