Amazon DocumentDB (MongoDB-compatible) increased its maximum cluster storage limit from 128 TiB to 256 TiB, enabling management of larger datasets in a single cluster. Storage scales automatically with data volume without upfront provisioning, simplifying scalability for data-intensive applications.
This upgrade requires engine version updates and is available in all AWS regions supporting DocumentDB. The service remains serverless and fully managed with features for security, backups, read replicas, and multi-region replication. Pricing is usage-based only; no independent verification of performance at scale has been noted.
