Sub‑100-ms APIs emerge from disciplined architecture using latency budgets, minimized hops, async fan‑out, layered caching, circuit breakers, and strong observability. But long‑term speed depends on culture, with teams owning p99, monitoring drift, managing thread pools, and treating performance as a shared, continuous responsibility.

AWS has introduced Intelligent-Tiering and cross-region replication for S3 Tables to automate cost optimization and data availability for Apache Iceberg workloads. These features allow data to transition to lower-cost storage tiers based on access patterns while maintaining consistent, read-only table replicas across regions and accounts without manual synchronization.

DuckDB has recently introduced end-to-end interaction with Iceberg REST Catalogs directly within a browser tab, requiring no infrastructure setup. The new feature leverages DuckDB-Wasm, a WebAssembly port of DuckDB that runs in the browser, allowing users to query, read, and write Iceberg tables in a serverless manner.
