R2 SQL - R2 SQL now supports approximate aggregation functions

R2 SQL now supports five approximate aggregation functions for fast analysis of large datasets. These functions trade minor precision for improved performance on high-cardinality data. New functions APPROX_PERCENTILE_CONT(column, percentile) — Returns the approximate value at a given percentile (0.0 to 1.0). Works on integer and decimal columns. APPROX_PERCENTILE_CONT_WITH_WEIGHT(column, weight, percentile) — Weighted percentile calculation where each row contributes proportionally to its weight

Building fault-tolerant applications with AWS Lambda durable functions

Business applications often coordinate multiple steps that need to run reliably or wait for extended periods, such as customer onboarding, payment processing, or orchestrating large language model inference. These critical processes require completion despite temporary disruptions or system failures. Developers currently spend significant time implementing mechanisms to track progress, handle failures, and manage resources when […]

LLM Inference Benchmarking - Measure What Matters

Production-grade LLM inference is a complex systems challenge, requiring deep co-designs - from hardware primitives (FLOPs, memory bandwidth, and interconnects) to sophisticated software layers - across the entire stack. Given the hardware variability across GPU providers like NVIDIA and AMD - including generational differences in numeric type performance (FP8, BF16, NVFP4 etc), HBM bandwidth and capacity, peak FLOPs etc - optimal performance is never guaranteed. It depends on the software’s abi
