Queue System

QueueProcessor

Static methods:

• processQueue(batchSize) — process queued + retry failed posts
• processEvergreen() — re-share evergreen articles on schedule
• retryPosts(postIds) — manually re-queue failed posts
• retryService(serviceId) — bulk retry all failed for a service
• hasPendingWork() — check if queue has items

Retry Mechanism

• Failed posts auto-retry up to retry_max times (default 3)
• Exponential backoff: retry_delay * 2^retry_count seconds
• After max retries: status set to permanently_failed
• Manual retry resets status to queued and retry_count to 0

Post Statuses

queued, posting, posted, failed, permanently_failed, cancelled, scheduled

Concurrency

Uses MySQL advisory lock (GET_LOCK) to prevent concurrent processing.
