Mar 1, 2026

March 2026 monthly summary for expectedparrot/edsl focusing on business value and technical achievements. Key features delivered include an OpenAI async integration using the aiohttp backend with a larger Redis pool to support higher concurrency and reduce MaxConnectionsError, plus selective Nest AsyncIO gating to enable uvloop-based speedups in production. RedisStorage was hardened with retry_on_error, health checks, and keepalive to prevent job stalls when Memorystore idle connections occur. Major performance improvements were achieved in Survey.draw (≈140x speedup) by skipping expensive dag() and YAML snapshot steps for internal copies. FileStore uploads to GCS were accelerated with a progress indicator and concurrent uploads (up to 20 threads). State persistence saw improved save and update semantics to preserve progress across operations. Additional reliability and observability gains include granular timing instrumentation for build_edsl_result and CI workflow/test fixes to stabilize the pipeline. These deliverables collectively improved throughput, reliability, and developer productivity while maintaining correctness across edge cases.
