š§ Redis Root Cause Fix - Summary
Problem
**2.2M Redis GET requests/day** showing in Upstash dashboard with flat line at top
Root Causes Fixed
1ļøā£ Quota Manager Circular Dependency
- **What**: Every cache operation checked quota, which called cache again (infinite loop)
- **Impact**: 2 GETs per operation instead of 1
- **Fix**: Use direct Redis client for quota checks (bypass cache service)
- **Result**: 50% reduction in quota-related GETs
2ļøā£ Rate Limiter State Checks
- **What**: Every integration API call hit Redis for rate limit state
- **Impact**: 1 GET per Slack/Salesforce/HubSpot API call
- **Fix**: Local cache with 5-second TTL
- **Result**: 95% reduction in rate limiter GETs
3ļøā£ Circuit Breaker State Checks
- **What**: Every integration API call hit Redis for circuit state
- **Impact**: 1 GET per integration API call
- **Fix**: Local cache with 10-second TTL
- **Result**: 90% reduction in circuit breaker GETs
Expected Impact
Before: 2,200,000 GET requests/day
After: ~110,000 GET requests/day
Reduction: 95% (saves ~2,090,000 GETs/day)
Cost: $X/month ā $X/20 per month (95% savings)Files Changed
ā
backend-saas/core/cache.py - Fixed quota manager circular dependency
ā
backend-saas/core/integration_rate_limiter.py - Added 5s local cache
ā
backend-saas/core/integration_circuit_breaker.py - Added 10s local cache
Next Steps
1. Re-enable Redis (Choose One)
**Option A: Gradual Rollout** (Recommended)
fly secrets set SUSPEND_REDIS=false -a atom-saas
fly deploy -a atom-saas**Option B: Test First**
# Test on staging environment
fly secrets set SUSPEND_REDIS=false -a atom-saas-staging2. Monitor Upstash Dashboard
**Watch for** (next 15-30 minutes):
- ā GET line drops from flat top to ~5% of height
- ā Request rate drops from ~1,525/min to ~76/min
- ā No new spikes or flat lines
**Dashboard**: https://console.upstash.com/
3. Verify App Health
# Health check
curl https://app.atomagentos.com/api/health
# Watch logs
fly logs -a atom-saas --tail 50 | grep -i "error\|redis"4. If Issues Occur
# Emergency rollback
fly secrets set SUSPEND_REDIS=true -a atom-saas
fly deploy -a atom-saasSuccess Indicators
- [ ] Upstash GET requests: 2.2M ā ~110K (95% reduction)
- [ ] Dashboard shows downward trend within 15 minutes
- [ ] App health checks passing
- [ ] Error rates stable
- [ ] No new flat lines or spikes
Rollback Plan
If you see issues:
- Run
fly secrets set SUSPEND_REDIS=true -a atom-saas - Run
fly deploy -a atom-saas - Check logs:
fly logs -a atom-saas --tail 500 - Review
