Celery Foundation

Use when building a distributed task queue or job worker: at-least-once ack/reject semantics across early/late modes, retry ladders (manual Task.retry, autoretry wrapper, exponential backoff with full jitter), prefork pool with event-loop time limits, bootstep blueprint startup/shutdown graphs, broker reconnect loops, ETA/countdown timers, beat's reentrant heap scheduler with crontab DST math, gossip worker elections, and mailbox-based remote control.

Celery: Distributed Task Queue Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: celery; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@8d2bccca0478cad48f31a75eaebc0ce389f65425.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Execution spine; Retry & timeouts; Pool; Boot & connect; Heartbeat & gossip; Beat scheduling; Results & control; Producer & cluster.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
