SESSION_BACKEND=redis          # redis | cloudsql | inmemory
MEMORY_BACKEND=cloudsql        # redis | cloudsql | inmemory

# Redis config
REDIS_URL=redis://host:6379/0
REDIS_SESSION_TTL=3600         # Seconds

Common Commands

# Start Redis locally
docker run -d -p 6379:6379 redis:7-alpine

# Test connection
redis-cli ping

# Run bot
python slack_bot.py

# Benchmark
python benchmark_session_performance.py

# Monitor Redis
redis-cli MONITOR

# Check sessions
redis-cli KEYS "session:*"

Emergency Rollback

# Fastest: Change env var
SESSION_BACKEND=cloudsql python slack_bot.py

# Production
gcloud run services update ifriend-slack-bot \
  --set-env-vars=SESSION_BACKEND=cloudsql

📞 Support

Issues?

  1. Check: REDIS_ROLLBACK_GUIDE.md → Troubleshooting
  2. Test: Connection with redis-cli ping
  3. Fallback: SESSION_BACKEND=inmemory (temporary)
  4. Logs: python slack_bot.py 2>&1 | grep -i redis

Performance Issues?

  1. Run: python benchmark_session_performance.py
  2. Verify: Backend in use (logs should show "Session Backend: redis")
  3. Check: Redis latency with redis-cli --latency

Production Issues?

  1. Immediate: Update env var to SESSION_BACKEND=cloudsql
  2. Investigate: Check Memorystore status
  3. Rollback: Follow REDIS_ROLLBACK_GUIDE.md
