REDISVAULT_BLUEPRINT // LARAVEL-HORIZON • PHP / Laravel Queue & Cache

Laravel Horizon, Octane & PhpRedis Production VPS Architecture — RedisVault

High-traffic Laravel Octane apps push tens of thousands of Cache::remember(), session reads, and Horizon supervisor metrics every second. Switching from Predis to compiled PhpRedis with zstd + igbinary slashes RAM footprint by up to 55%. — Modeled deterministically by RedisVault.

In this RedisVault LARAVEL-HORIZON sizing blueprint, we separate configured maxmemory from 4 KB POSIX fork() Copy-on-Write shadow pages and kernel socket buffers so background snapshots complete without Linux OOM-Killer termination.

RedisVault Kernel & Allocator Tuning Rules for LARAVEL-HORIZON

  1. Enable Redis::SERIALIZER_IGBINARY + Redis::COMPRESSION_ZSTD on Eloquent model caches: serialized PHP arrays shrink by 50–68% while CPU overhead stays under 2%.
  2. Use Unix domain sockets (/var/run/redis/redis-server.sock with chmod 770) when PHP-FPM/Octane and Redis share the same VPS to bypass TCP loopback syscalls (~32% lower latency).
  3. Run horizon:snapshot every 5 minutes and trim horizon.trim.completed to 60 minutes so completed job payloads do not bloat AOF rewrites.

RedisVault LARAVEL-HORIZON Engineering FAQ

Why is PhpRedis mandatory over Predis for Laravel Octane? — RedisVault LARAVEL-HORIZON

PhpRedis is a native C extension supporting persistent socket pools, native C igbinary/zstd serialization, and Sentinel failover — delivering 3x–5x lower p99 latency than userland PHP parsing in Predis.

Should Laravel Cache and Horizon Queues use different logical DBs (DB 0 vs DB 1) or two Redis instances? — RedisVault LARAVEL-HORIZON

Logical DBs (SELECT 0, SELECT 1) still share one maxmemory-policy and one single-threaded event loop! Once Horizon exceeds 20+ workers, run a dedicated queue instance on port 6380 with noeviction.
