Storage Scan

It is common to have large data sets partitioned across a large number of hosts or databases, or having billions of files in an Amazon S3 bucket. Temporal is an ideal solution for implementing the full scan of such data in a scalable and resilient way. The standard pattern is to run an activity (or multiple parallel activities for partitioned data sets) that performs the scan and heartbeats its progress back to Temporal. In the case of a host failure, the activity is retried on a different host and continues execution from the last reported progress.

A real-world example:

  • Temporal internal system workflow that performs periodic scan of all workflow execution records
