IcebergTableAdapter

An IcebergTableAdapter is a class that manages an Iceberg table and provides methods to interact with it.

Constructors

The IcebergTableAdapter class can be constructed directly:

It can also be constructed using an IcebergCatalogAdapter load_table method:

Parameters

If constructed directly, the parameters are:

  • catalog: The Iceberg catalog to use.
  • tableIdentifier: The identifier of the Iceberg table.
  • table: The Iceberg table.
  • dataInstructionsProviderLoader: A loader for data instructions.
  • resolver: A resolver for the table.
  • nameMapping: The name mapping for the table.

If constructed using IcebergCatalogAdapter.load_table, the parameter is:

  • tableIdentifier: The identifier of the Iceberg table to load.

Methods

  • catalog: Return the catalog used to access the Iceberg table.
  • currentSchema: Retrieve the current schema of the Iceberg table.
  • currentSnapshot: Get the current snapshot of the Iceberg table.
  • definition: Get the definition of the Iceberg table.
  • definitionTable: Get a table representation of the Iceberg table definition.
  • getSnapshot: Retrieve a specific snapshot of the Iceberg table by its ID.
  • icebergTable: Return the underlying Iceberg table.
  • listSnapshots: List all snapshots of the Iceberg table.
  • locationUri: Get the location URI of the Iceberg table.
  • nameMapping: Get the name mapping used for the Iceberg table.
  • provider: Return the table location provider.
  • refresh: Refresh the Iceberg table metadata.
  • resolver: Get the resolver for the Iceberg table.
  • schema: Get the identifier of the schema to load.
  • schemas: List all schemas of the Iceberg table as a Deephaven table.
  • snapshots: List all snapshots of the Iceberg table as a Deephaven table.
  • table: Read the latest snapshot of the Iceberg table as a Deephaven table.
  • tableIdentifier: Get the identifier of the Iceberg table.
  • tableWriter: Create a new IcebergTableWriter for this Iceberg table using the provided options.
  • toString: Get a string representation of the Iceberg table adapter.

Examples

The following example constructs an IcebergCatalogAdapter and uses it to create an IcebergTableAdapter for a specific table. It uses the Docker deployment defined in the Deephaven and Iceberg guide.
