The Teradata Access Module for Azure Blob supports normal checkpoint and restart/recovery operations in the data import scenario, where data is loaded into a database, but not in the data export scenario, where data is exported from a database.

The Teradata Parallel Transporter DataConnector operator issues the File Set Position command and provides the file offset to the Teradata Access Module for Azure Blob when a Teradata Parallel Transporter job terminates unexpectedly and restarts.

The Teradata Access Module for Azure Blob repositions to the file offset provided by the Teradata Parallel Transporter DataConnector operator and starts reading the data.
