How to aggregate timeseries data to enable archiving

Working with Data

Hi @michael_hoeller ,

This seems to be the classic use case of using online archive in Atlas and than to use a federated connection string to access data in both cluster and MongoDB archive storage.

Another option is to use the preImage option in a delete trigger for the ttl deletes .

So each ttl delete will allow you to write the data to your archive destination and precompute as needed.

Thanks
