SystemTechniques · 16Primitives · 67 ipaas Template enginescompilers · medium: Compile templates with loops, partials and auto-escaping into render functionsDAG workflow executiondistributed · medium: Run a graph of dependent tasks by releasing each one when its inputs are done, longest chain first, and skip any task whose input hashes are unchanged.›Deterministic simulation testingdistributed · medium: Run the whole system in one thread under a seeded scheduler with simulated network, disk and clock, so every failure replays from its seed.›Durable workflow executiondistributed · medium: Ordinary code made crash-proof by logging every side-effect result and replaying the code from that log; activities run at least once, workflow logic must be deterministic.›Incremental sync cursorsdistributed · medium: The client keeps one opaque token; each pull returns only the changes after it plus the next token, so sync cost scales with what changed, not with the dataset.›Primary-backup replicationdistributed · medium: One node orders all writes and ships them to standbys; the acknowledgement rule (none, one, all) sets what a crash loses, and an external arbiter decides who takes over.›Webhook deliverynetworking · medium: Reliable server-to-server HTTP callbacks: signed POSTs, 2xx-means-done, retries over days with jitter, endpoint disabling, SSRF guards and idempotent receivers.›Exponential backoff with jittersystems · low: Retry after delays that grow geometrically and are randomized, so failed clients spread out instead of hammering a recovering service in synchronized waves.›Cursor paginationnetworking · low: Keyset/opaque-cursor pagination for stable incremental reads from APIs and tablesDead-letter queuedistributed · low: A side queue for messages that keep failing: after N delivery attempts or a permanent error, park them with the reason so the main queue keeps moving.›Idempotency keysfinance · low: Client-chosen unique key per logical operation, stored with a request fingerprint and the final response, so retries replay the first result instead of acting twice.›Hmac request signingsecurity · low: HMAC canonical-request signatures and presigned URLs (SigV4 style) with expiryPratt parsingcompilers · low: Table-driven expression parsing with one loop and a numeric binding power per operator; the compact core of precedence handling in hand-written parsers.›Hdr histogramdata-structures · low: Log-linear bucketed histograms with bounded relative error for latency percentilesEvent deduplication windowdistributed · low: Keep the ids of recently accepted events for a time window and drop repeats; memory stays bounded by rotating time buckets instead of per-entry timers.›Process supervisionhardware-os · low: A parent process starts services, reaps their exits and restarts them under a delay and burst-limit policy, then stops them with SIGTERM before SIGKILL.›JSON Schema validationsecurity · low: Compile a JSON Schema once, then check every untrusted document against it, within hard size and depth limits, and report failures as JSON Pointers.›Mutual TLSsecurity · low: TLS where the client also proves a certificate key, so every connection carries a verified, rotatable machine identity.›OAuth 2 and OpenID Connectsecurity · low: Delegated authorization (OAuth 2) and login on top of it (OIDC); use authorization code + PKCE for every user-facing client.›Secrets managementsecurity · low: Keep keys and passwords out of code and logs, give workloads short-lived identity instead of static keys, and make rotation routine.›Schema inferencestorage · low: Infer column types and structure from sample recordsCron schedulingsystems · low: Cron expression parsing and next-fire-time computation, with catch-up and time-zone rulesGraceful drainingsystems · low: On a termination signal, stop taking new work, finish in-flight work until a deadline, tell clients to reconnect elsewhere, then exit; clients resume from a token.›+ 9 more techniques+ 51 more primitives
