AWS documentdb documentation change
Summary
Removed entire documentation page for the $zip operator in Amazon DocumentDB, including examples and code samples.
Security assessment
The change removes an entire documentation page without any mention of security vulnerabilities, weaknesses, or incidents. This appears to be routine documentation cleanup or restructuring, not related to addressing a security issue.
