      • initialize

        public void initialize​(java.lang.String name,
                               java.util.Map<java.lang.String,​java.lang.String> properties)
        Description copied from interface: Catalog
        Initialize a catalog given a custom name and a map of catalog properties.

        A custom Catalog implementation must have a no-arg constructor. A compute engine like Spark or Flink will first initialize the catalog without any arguments, and then call this method to complete catalog initialization with properties passed into the engine.

        Specified by:
        initialize in interface Catalog
        name - a custom name for the catalog
        properties - catalog properties
      • name

        public java.lang.String name()
        Description copied from interface: Catalog
        Return the name for this catalog.
        Specified by:
        name in interface Catalog
        this catalog's name
      • createNamespace

        public void createNamespace​(Namespace namespace,
                                    java.util.Map<java.lang.String,​java.lang.String> metadata)
        Description copied from interface: SupportsNamespaces
        Create a namespace in the catalog.
        Specified by:
        createNamespace in interface SupportsNamespaces
        namespace - a multi-part namespace
        metadata - a string Map of properties for the given namespace
      • listTables

        public java.util.List<TableIdentifier> listTables​(Namespace namespace)
        Description copied from interface: Catalog
        Return all the identifiers under this namespace.
        Specified by:
        listTables in interface Catalog
        namespace - a namespace
        a list of identifiers for tables
      • dropTable

        public boolean dropTable​(TableIdentifier identifier,
                                 boolean purge)
        Description copied from interface: Catalog
        Drop a table; optionally delete data and metadata files.

        If purge is set to true the implementation should delete all data and metadata files.

        Specified by:
        dropTable in interface Catalog
        identifier - a table identifier
        purge - if true, delete all data and metadata files in the table
        true if the table was dropped, false if the table did not exist

      • defaultLocationProperty

        public static java.lang.String defaultLocationProperty()
        The property used to set a default location for tables in a namespace. Call setProperties(Namespace, Map) to set a path value using this property for a namespace, then all tables in the namespace will have default table root path under that given path.
