feat(redrive): DLQ redrive tooling — safe replay (ADR-0026)#3
Merged
Conversation
The Node mirror of babelqueue-go/redrive.go. Since the core is codec-only, redrive(io, dlq, opts) takes a small RedriveIO (pop/publish) over the caller's transport, and resetForRedrive(env) is the pure core: strip dead_letter, attempts->0, preserve job/trace_id/data/meta. Options toQueue (sandbox), max, dryRun, select. Drains-then-processes; restores skipped/dry-run/undecodable bodies; restores + re-throws on a publish failure. A normal root export (no dependency). Envelope frozen (GR-1); Replay-Bypass header is a documented phase two.

babelqueue-go/redrive.go(ADR-0026) — DLQ inspect/redrive, the operator tool the contract deferred.What
Because the Node core is codec-only (no runtime / no transport), the shape adapts the way the optional
otel.publishhelper did:resetForRedrive(envelope): Envelope— the pure, transport-free core: strip thedead_letterblock, resetattemptsto 0, preservejob/trace_id/data/metaverbatim (input not mutated).redrive(io, dlq, opts)— drains a DLQ via a smallRedriveIO(pop/publish) the caller implements over their transport, and re-publishes each reset message to itsdead_letter.original_queueoropts.toQueue. Options:toQueue(sandbox),max,dryRun,select. Drains-then-processes; restores skipped/dry-run/undecodable bodies (never drops); on a publish failure restores to the DLQ and re-throws; acks only after a successful re-publish.A normal root export (
src/redrive.ts→src/index.ts) — pure, no dependency. The envelope stays frozen (GR-1).Tests / gate

The Replay-Bypass guard (a
bq-replay-bypasstransport header so a replay can skip external side-effects) is a documented phase two — it touches the runtime + every transport, like ADR-0025'straceparentfollow-up.🤖 Generated with Claude Code
