I have a Cosmos DB database with multiple containers using shared throughput autoscaling, 400 to max 4000.
In the Monitoring Insights (preview) I noticed higher throughput every hour. I tried finding the container this is for by selecting the throughput tab and setting the database and then trying each container, but I can't see the same pattern as when it is set to unset.
Then at the bottom of the screen I noticed that under Provisioned Throughput (Max) by Collection, it specifies the __empty collection and that has a value of 800.
What is the __empty collection?
