From 779c38d4ca9b808ceae12ad0e5dd043fd77c3ce7 Mon Sep 17 00:00:00 2001 From: abretonc7s Date: Thu, 10 Apr 2025 11:02:28 +0800 Subject: [PATCH 01/24] feat(redis): implement connection pooling and key migration for Redis - Introduced a connection pool for Redis to improve resource management and reduce connection churn. - Added backward compatibility for Redis key formats, migrating legacy keys to new formats during access. - Enhanced metrics for tracking key migration progress and connection pool health. - Updated Redis client interactions across the application to utilize the new pooling mechanism. - Implemented health checks and logging for Redis connections to improve operational visibility. --- packages/sdk-socket-server-next/CHANGES.md | 28 ++ packages/sdk-socket-server-next/package.json | 4 +- .../src/analytics-api.ts | 366 ++++++++++++++++-- .../sdk-socket-server-next/src/metrics.ts | 27 ++ .../src/protocol/handleAck.ts | 38 +- .../src/protocol/handleChannelRejected.ts | 125 +++--- .../src/protocol/handleCheckRoom.ts | 31 +- .../src/protocol/handleJoinChannel.ts | 47 ++- .../src/protocol/handleMessage.ts | 42 +- .../src/protocol/handlePing.ts | 2 +- .../src/protocol/retrieveMessages.ts | 40 +- .../sdk-socket-server-next/src/redis-check.ts | 31 +- packages/sdk-socket-server-next/src/server.ts | 11 + .../src/socket-config.ts | 20 +- yarn.lock | 62 ++- 15 files changed, 726 insertions(+), 148 deletions(-) create mode 100644 packages/sdk-socket-server-next/CHANGES.md create mode 100644 packages/sdk-socket-server-next/src/server.ts diff --git a/packages/sdk-socket-server-next/CHANGES.md b/packages/sdk-socket-server-next/CHANGES.md new file mode 100644 index 000000000..7876ab0c8 --- /dev/null +++ b/packages/sdk-socket-server-next/CHANGES.md @@ -0,0 +1,28 @@ +# Changelog + +## Redis Connection Management Improvements + +1. **Connection Pool Implementation** + - Replace the singleton Redis client with a properly managed connection pool + - Reduce minimum connections from 15 to 3 for startup efficiency + - Increase maximum connections to 50 for high-throughput scenarios + - Configure pool parameters via environment variables (REDIS_POOL_MIN, REDIS_POOL_MAX) + +2. **Socket.IO Redis Adapter Integration** + - Ensure Socket.IO cluster support with proper Redis adapter configuration + - Fix compatibility issues between Socket.IO and ioredis library + +3. **Monitoring and Metrics** + - Add Redis pool metrics for connection usage tracking + - Add API endpoint for monitoring pool health (/redis-pool-stats) + - Log connection pool statistics for better operational visibility + +4. **Improved Stability** + - Add graceful shutdown to properly close Redis connections + - Implement health checking with automatic connection recovery + - Validate connections to ensure they're working properly + +5. **Backward Compatibility** + - Maintain existing API through proxy mechanism + - Support existing key migration patterns + - Fix redundant connection logs diff --git a/packages/sdk-socket-server-next/package.json b/packages/sdk-socket-server-next/package.json index b5c8b77c2..fda7aacfc 100644 --- a/packages/sdk-socket-server-next/package.json +++ b/packages/sdk-socket-server-next/package.json @@ -49,14 +49,14 @@ "express-rate-limit": "^7.1.5", "generic-pool": "^3.9.0", "helmet": "^5.1.1", - "ioredis": "^5.3.2", + "ioredis": "^5.6.0", "logform": "^2.6.0", "lru-cache": "^10.0.0", "prom-client": "^15.1.3", "rate-limiter-flexible": "^2.3.8", "redis": "^4.6.12", "rimraf": "^4.4.0", - "socket.io": "^4.4.1", + "socket.io": "^4.7.2", "uuid": "^9.0.1", "winston": "^3.11.0", "winston-loki": "^6.0.8" diff --git a/packages/sdk-socket-server-next/src/analytics-api.ts b/packages/sdk-socket-server-next/src/analytics-api.ts index 1ee2e3e17..0c8f4cacf 100644 --- a/packages/sdk-socket-server-next/src/analytics-api.ts +++ b/packages/sdk-socket-server-next/src/analytics-api.ts @@ -24,6 +24,7 @@ import { incrementAnalyticsError, incrementAnalyticsEvents, incrementRedisCacheOperation, + incrementKeyMigration, } from './metrics';

Use `docker compose down -v` to remove data volumes when stopping containers if you need a clean slate. +- **Logs**: Check container logs using `docker compose logs ` (e.g., `docker compose logs app1`). +- **Security**: Be cautious when exposing services via Ngrok. diff --git a/packages/sdk-socket-server-next/docker-compose.yml b/packages/sdk-socket-server-next/docker-compose.yml index ee9927d69..82a186f93 100644 --- a/packages/sdk-socket-server-next/docker-compose.yml +++ b/packages/sdk-socket-server-next/docker-compose.yml @@ -107,3 +107,64 @@ services: -

Added Loki and Promtail services to the Docker Compose setup for centralized log management. - Configured Promtail to scrape logs from Docker containers based on labels for better observability. - Created a new Grafana dashboard for visualizing logs and metrics from the socket server and Redis. - Updated README with instructions for starting the new logging stack alongside existing services. - Removed the default Grafana dashboard in favor of a more comprehensive logging dashboard. --- packages/sdk-socket-server-next/README.md | 4 +- .../sdk-socket-server-next/docker-compose.yml | 109 +- .../grafana/dashboards/basic.json | 218 + .../grafana/dashboards/default-dashboard.json | 218 -
