3 docs tagged with "idempotency"

Leader election with fencing tokens, hierarchical timing wheels, lease-based worker eviction, idempotent execution, and the thundering herd at every :00.

Cross-channel deduplication, provider failover, quiet hours across time zones, priority lanes so OTPs never queue behind marketing, and 100M-user broadcasts.

Idempotency under unknown outcomes, immutable double-entry ledgers in integer cents, saga orchestration with compensations, bank-file reconciliation, PCI scope, and multi-currency.
