go.redis.connection_pool

Scalability High

Detects missing or misconfigured Redis connection pool settings.

Why It Matters

Missing connection pool configuration:

Connection exhaustion — Too many connections overwhelm Redis
Resource waste — Idle connections consume memory
Timeouts — No pool limits lead to starvation

Example

// ❌ Before (no pool configuration)
client := redis.NewClient(&redis.Options{
    Addr: "localhost:6379",
})

// ✅ After (with connection pool settings)
client := redis.NewClient(&redis.Options{
    Addr:         "localhost:6379",
    PoolSize:     100,
    MinIdleConns: 10,
    PoolTimeout:  30 * time.Second,
    MaxRetries:   3,
})

What Unfault Detects

Missing PoolSize configuration
Missing MinIdleConns
Missing PoolTimeout
Unreasonable pool size values

Auto-Fix

Unfault can add appropriate connection pool configuration based on common best practices.
