Background processing patterns to ensure reliable, idempotent, and scalable queue execution across multiple workers and systems.
Review existing workers, adopt atomic claim patterns, implement backoff, and add dead-letter handling to new queues.

Prevent duplicate work in background queue processing by using atomic queue claims with FOR UPDATE SKIP LOCKED, ensuring multiple workers safely claim unique jobs without overlapping execution. This pattern coordinates reliable, scalable processing across concurrent workers.
Handle failed background jobs safely by implementing exponential backoff for transient errors and dead-letter handling for permanent failures. This robust retry logic ensures safe re-execution while isolating problematic jobs to prevent quota waste and data loss.
Checkpointing for reliable queue workers saves execution progress so interrupted jobs can resume without restarting from the beginning. Combined with stale-lock detection and echo-detection, it prevents infinite retry loops and ensures idempotent processing across system failures.
Background queue workers get stuck on stale locks when prior execution crashes leave rows permanently locked. Implement stale-lock detection and recovery patterns to identify abandoned jobs and safely re-queue them, preventing system bottlenecks and avoiding duplicate work during retries.
Yes, you can use these background queue patterns for email_queue and sync workers like rex_sync_queue and rex_sync_retry_queue. The atomic updates, backoff, and checkpointing mechanisms apply broadly to any system requiring reliable, idempotent background job execution.
