Certificate compression support for TLS connections


What problem are you trying to solve?

Focus on the what and why of the need you have, not the how you'd like it solved.

There is an open PR in Node.js for TLS (1.3+) certificate compression via a new certificateCompression option in the TLS API.

What would you like to see happen?

Describe the desired outcome or enhancement.

The Node driver could expose this option in the client configuration.

This idea would be a prereq: Support TLS1.3 in Atlas Control Plane and Clusters

Why is this important to you or your team?

Explain how the request adds value or solves a business need.

This can reduce handshake size and improve connection performance, especially for serverless, connection-heavy, or x.509-based workloads, when the server supports RFC 8879.

What steps, if any, are you taking today to manage this problem?
