Implement Outbox Pattern with consumer ACK to ensure 100% reliable event delivery between blockchain-service and wallet-service: blockchain-service: - Add OutboxEvent model to Prisma schema with status tracking - Create outbox repository interface and implementation - Modify deposit-detection.service to write events to outbox - Add outbox-publisher.service with cron jobs for publishing/retry - Add deposit-ack-consumer.service to receive ACK from wallet-service - Add publishRaw method to event-publisher.service wallet-service: - Modify deposit-confirmed.handler to send ACK after successful processing - Add wallet.deposit.credited topic mapping for ACK events Event flow: 1. Deposit detected → written to outbox (status: PENDING) 2. Outbox publisher sends to Kafka → status: SENT 3. wallet-service processes and sends ACK → status: ACKED 4. Events without ACK are retried with exponential backoff 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> |
