AWS documentdb documentation change
Summary
Entire documentation page for the $collStats aggregation stage has been removed, including all content, examples, and code samples
Security assessment
This change removes documentation for a database aggregation command but provides no evidence of security vulnerability, weakness, or incident. The removal appears to be a routine documentation cleanup or restructuring, not related to any security issue. The content removed was purely functional documentation about using the $collStats command to retrieve collection statistics.
