DocumentDB waste check
Idle DocumentDB
idle_documentdb
What it finds
Idle DocumentDB: one of the DocumentDB checks in the database optimization group. Checks in this group look for: database capacity that is idle, oversized for its load, kept past its useful life, or priced on a mode that does not fit how it is used.
Why it costs money
Managed databases bill for provisioned instances, storage and backups around the clock, so unused or oversized capacity is a standing cost.
How it is detected
Runs in the partner build and the paid hosted tiers.
AWS's own tools
AWS flags this too, under "Idle recommendation for DocumentDB clusters".
Checked against the AWS documentation.
Where this check runs
This check ships in the partner build, for consultancies that scan client accounts, and in the paid hosted tiers.
