Amazon DocumentDB Planner V2.0 Improves Query Performance
🚀 Amazon DocumentDB (with MongoDB compatibility) introduces PlannerVersion 2.0 for DocumentDB 5.0, delivering advanced query optimization and up to 10x performance improvements for indexed find and update operations. The new planner improves cost estimation, selects more optimal index plans, and adds index-scan support for negation operators such as $neq and $nin, as well as nested $elementMatch. Enabling PlannerVersion 2.0 requires a simple parameter change in your cluster parameter group and does not require a restart or incur downtime; you can revert to the legacy planner if needed.
