# AWS adds post-quantum TLS and MongoDB APIs to DocumentDB

_Published Tuesday, November 10, 2026 at 11:41 PM EST · Science, Infrastructure · Latest · Tier 2 — Notable_

AWS made Amazon DocumentDB 8.0.3 available in every AWS Region offering the database service, adding hybrid post-quantum TLS and MongoDB-compatible features. AWS says the new APIs allow more MongoDB workloads to move to DocumentDB without application code changes.

TLS 1.3 connections use ML-KEM, a method for exchanging encryption keys designed to resist quantum attacks, when clients support it. Other clients continue using classical key exchange, and new CloudWatch metrics count both handshake types.

Wildcard indexes support queries across documents with changing fields. The $unionWith aggregation stage combines results from multiple collections in one processing pipeline.
