The 8.0.2 release of Amazon DocumentDB (MongoDB-compatible) expanded its API support with retryable writes to improve resilience in network failovers. It added new aggregation pipeline stages including $setWindowFields, $bucketAuto, $facet, $graphLookup, and correlated $lookup, enabling more advanced data analytics and hierarchical queries.
Change stream capabilities improved with splitting large events and emitting createCollection/createIndex operations. Query execution enhancements include index-only scans, support for $expr predicate indexes, incremental sorts, and faster count operations. These enhancements made migrating MongoDB workloads easier and boosted performance, available in all DocumentDB-supported AWS regions as of 2026.
