Snapshots

Snapshots configuration is straightforward. You can set the creation_rate - a cron schedule for creating new snapshots (every 30 minutes by default). See CronExpression docs for details.

The second option is keep_empty. If set to true, the links to entities that are null (i.e., no such entity exists) will create an empty entity for the purpose of the snapshot, and these entities will be saved as snapshots that batch. Otherwise, the null links will be deleted. This option is true by default.

File snapshots.yml looks like this:

creation_rate:
  minute: "*/30"

keep_empty: true
