Constructor Detail

GlueCatalog

public GlueCatalog()

No-arg constructor to load the catalog dynamically.

All fields are initialized by calling initialize(String, Map) later.

Method Detail

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

Parameters:

name - a custom name for the catalog

properties - catalog properties

newTableOps

protected TableOperations newTableOps(TableIdentifier tableIdentifier)

Specified by:

newTableOps in class BaseMetastoreCatalog

defaultWarehouseLocation

protected java.lang.String defaultWarehouseLocation(TableIdentifier tableIdentifier)

This method produces the same result as using a HiveCatalog. If databaseUri exists for the Glue database URI, the default location is databaseUri/tableName. If not, the default location is warehousePath/databaseName.db/tableName

Specified by:

defaultWarehouseLocation in class BaseMetastoreCatalog

Parameters:

tableIdentifier - table id

Returns:

default warehouse path

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

Parameters:

namespace - a namespace

Returns:

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

Parameters:

identifier - a table identifier

purge - if true, delete all data and metadata files in the table

Returns:

true if the table was dropped, false if the table did not exist

renameTable

public void renameTable(TableIdentifier from,
                        TableIdentifier to)

Rename table in Glue is a drop table and create table.

Specified by:

renameTable in interface Catalog

Parameters:

from - identifier of the table to rename

to - new table 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

Parameters:

namespace - a multi-part namespace

metadata - a string Map of properties for the given namespace

listNamespaces

public java.util.List<Namespace> listNamespaces(Namespace namespace)
                                         throws NoSuchNamespaceException

Description copied from interface: SupportsNamespaces

List namespaces from the namespace.

For example, if table a.b.t exists, use 'SELECT NAMESPACE IN a' this method must return Namepace.of("a","b") Namespace.

Specified by:

listNamespaces in interface SupportsNamespaces

Returns:

a List of namespace Namespace names

Throws:

NoSuchNamespaceException - If the namespace does not exist (optional)

loadNamespaceMetadata

public java.util.Map<java.lang.String,java.lang.String> loadNamespaceMetadata(Namespace namespace)
                                                                       throws NoSuchNamespaceException

Description copied from interface: SupportsNamespaces

Load metadata properties for a namespace.

Specified by:

loadNamespaceMetadata in interface SupportsNamespaces

Parameters:

namespace - a namespace. Namespace

Returns:

a string map of properties for the given namespace

Throws:

NoSuchNamespaceException - If the namespace does not exist (optional)

dropNamespace

public boolean dropNamespace(Namespace namespace)
                      throws NamespaceNotEmptyException

Description copied from interface: SupportsNamespaces

Drop a namespace. If the namespace exists and was dropped, this will return true.

Specified by:

dropNamespace in interface SupportsNamespaces

Parameters:

namespace - a namespace. Namespace

Returns:

true if the namespace was dropped, false otherwise.
