Datastore cleaner

Diagram for Datastore cleaner system

Because the best data is the data you do not keep, I wanted to periodically clean up old entries from the database of The data is store in Google Cloud Datastore, so I built a tool to automatically clean up old Google Cloud Datastore entities.

I built a serverless microservice that deletes Cloud Datastore entities that are older than a certain age (at year by default), to be run as a cron job every day (using Cloud Scheduler)
It uses a Cloud Run microservice that is privately invoked every day by a Cloud Scheduler job. When invoked, it queries your Cloud Datastore for entities that are older than a year and deletes them. The entity name and attribute containing the date must be provided as parameters. The number of entities and the time period can be customized.
