Nov 1, 2025

In November 2025, delivered a critical memory-management fix for Redis-backed Bull queues in island.is, targeting production stability and memory efficiency. Implemented removal policies to prune Bull jobs: remove successful jobs and cap failed jobs at 1000 in Redis for session and file queues; upgraded Keyv to optimize memory usage and eliminated Redis sets usage by adopting @keyv/redis v4/v5 and migrating from ioredis to node-redis. Added age-based cleanup for finished jobs to replace count-based removal. Result: significantly reduced memory footprint and mitigated metadata buildup, improving throughput under load and reducing operational risk.
