BackFill - Data Management - Alibaba Cloud Documentation Center

Backfills data for a task flow.

Operation description

During a data backfill, task flows are run in sequence based on their dates. You can specify whether task flows are run in chronological or reverse chronological order. After the data backfill is complete, you can specify a date or date range, and a node range to run task flows.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
