Vector Store Update Function Enhancements

The update function now accepts the following new parameters:

  • alter_operation: Specifies the type of operation to perform for update (ADD/DROP).
  • update_style: Specifies the style to be used with alter_operation (MAJOR/MINOR).
  • object_names: Specifies the table name/teradataml DataFrame to be indexed for vector store.
  • ignore_embedding_errors: Specifies whether to ignore errors during embedding generation.
  • database_name: Specifies the database name where vector is created. User should have create table permission on this database.
  • batch: Specifies whether to use batch processing for embedding generation. Applicable only for aws.

Batch Processing Enhancements

  • Batch support is enabled for similarity_search, ask, and prepare_response APIs.
  • A new API get_batch_result is added to retrieve results after triggering the APIs in batch mode.

Content-Based Vector Store Enhancements

  • Content-based Vector Store can now be created on multiple tables/views.
  • The object_names parameter can be provided with a list of strings or list of DataFrame while creating a Vector Store.

Asynchronous Operations

  • Creating, updating, and deleting Vector Stores is now asynchronous.
  • The status API can be used to check the status of these operations.

General Enhancements

  • Errors that were previously displayed in a DataFrame column are now thrown as TeradatamlException.
  • DataFrame displayed to the user, except for status(), is now a teradataml DataFrame instead of a pandas DataFrame for better control.
  • Implemented get_details function which gets the details of the Vector Store.

Read/Write permissions are changed to User/Admin permissions.
