DataHubGc

DataHubGcSource is responsible for performing garbage collection tasks on DataHub.

This source performs the following tasks:

1. Cleans up expired tokens.
2. Truncates Elasticsearch indices based on configuration.
3. Cleans up data processes and soft-deleted entities if configured.

CLI based Ingestion

The datahub-gc source works out of the box with acryl-datahub.
