  Durable Workflows Can Be Built on `SQLite` Alone

  ObeliskWorkflow runtime — replays state from execution logs

  Durability comes from saved workflow state, not heavy infrastructure. If progress is replayable, SQLite is enough for small reliable job orchestration.

  • —The core requirement is persisted progress: reruns and recovery work once each workflow step leaves state behind.
  • —Obelisk stores workflow progress in an execution log and replays from durable history, matching activity retry patterns.
  • —This fits background jobs, billing retries, and AI task pipelines before adopting heavier queues or workflow platforms.

  `Shopify` Replaces Redis Inventory Reservations With MySQL

  ShopifyE-commerce SaaS — unified checkout and store ops

  Oversell prevention moved from cache-style reservations to transactional rows using SKIP LOCKED. Worth copying only when checkout correctness beats simple counter performance.

  • —MySQL 8 SKIP LOCKED lets workers claim available reservation rows without blocking the whole queue; useful for high-contention checkout paths.
  • —The redesign uses one row per sellable unit, not a quantity column. It trades table size for clearer locking and recovery semantics.
  • —The pattern fits limited-stock sales, tickets, and booking flows. For tiny catalogs, a simpler counter plus idempotent order checks is enough.

  How Container Registries Work: Push/Pull Images Directly

  40radar

  Registry bugs often hide below the docker push surface. Understanding blobs, tags, manifests, and platform metadata helps debug broken deploys faster.

  • —A registry is a content-addressable blob store; layers are referenced by digest, so missing blobs break pulls even when tags look valid.
  • —Tags are mutable pointers, not versions. Pinning image digests is safer for Vercel-style build pipelines and reproducible deploys.
  • —Platform mismatches come from manifest metadata. Multi-arch images need explicit checks before shipping ARM/local builds to x86 servers.
