source-0 (aws.amazon.com/whats-new): Official announcement page, confirms the update and April 20 2026 date. source-1 (AWS Database Blog): Primary technical source — confirmed 45% faster scaling (22 min vs 40 min from 0.5 to 256 ACU), HammerDB TPROC-C benchmark (27-34% NOPM improvement), Sysbench read-only (27% faster, 28% lower cost vs v3), Sysbench write-only (32.9% faster, 5.1% lower ACU consumption), authors Jiaming Yan/Ashok Kurakula/Nashad Safa confirmed. source-2 (InfoQ): Confirmed Corey Quinn and Pini Dibask quotes verbatim; Quinn quote in article is first sentence of multi-sentence quote — ends at natural sentence boundary 'tends to land.' Dibask quote is first clause of longer LinkedIn comment, ending with comma indicating truncation, but the key fact (35% discount, highest of any AWS database service) is accurate.

All quantitative claims verified against source-1. Benchmark figures (22 min, 40 min, 27 min/109 ACUs, 37 min/151 ACUs, 32.9%, 5.1%, 27-34% NOPM) all match source text precisely. Quote from Pini Dibask ends mid-sentence (after comma), but the factual content within the quoted portion is accurate. Quinn quote ends at a natural sentence boundary.

High-quality, technically accurate article with all claims verified from authoritative sources. Clean APPROVE.
