Amazon Aurora DSQL

Now provides statement-level cost estimates in query plans, giving developers immediate insight into the resources consumed by individual SQL statements. This enhancement surfaces Distributed Processing Unit (DPU) usage estimates directly within the query plan output, helping developers identify workload cost drivers, tune query performance, and better forecast resource usage.

With this launch, Aurora DSQL appends per-category (compute, read, write, and multi-Region write) and total estimated DPU usage at the end of the EXPLAIN ANALYZE VERBOSE plan output. The feature complements CloudWatch metrics by providing fine-grained, real-time visibility into query costs.

Aurora DSQL support for DPU usage in EXPLAIN ANALYZE VERBOSE plans is available in all Regions where Aurora DSQL is available.
