The Teradata Access Module for Azure supports normal checkpoint and restart/recovery operations in the data import scenario, where data is loaded into the Teradata Database, but not in the data export scenario, where data is exported from the Teradata 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 when a Teradata Parallel Transporter job terminates unexpectedly and restarts.

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