AWS documentdb documentation change
Summary
Entire documentation page for the $size aggregation operator has been removed, including examples in MongoDB Shell, Node.js, and Python.
Security assessment
This change removes documentation content entirely but shows no evidence of addressing a security vulnerability. The removed content includes standard aggregation operator examples without any security context or vulnerability mentions. This appears to be part of a documentation cleanup or reorganization, possibly consolidating $size operator documentation elsewhere.
