VertexCache

🚀 VertexCache is Now Live — June 30, 2025

VertexCache is officially live and ready for early adopters. Actively refining features, SDKs, and documentation — contributions and feedback are welcome.

VertexCache is a fast, secure, open-source in-memory caching system built for modern workloads.
Designed as a developer-first solution, VertexCache combines multi-index lookups, wire-efficient messaging, and built-in encryption — all optimized for performance and control.

Lightweight by design. Secure by default. High-performance TCP clients in your language of choice.

Our Mission

To do one thing and do it well — caching — guided by the core tenets of Security, Flexibility, and Simplicity.

Why VertexCache?

Multi-Index Caching — Query by primary, secondary, or tertiary keys
Multi-Tenant Support — Isolate tenants and enforce role-based access with the AuthModule
Custom Binary Protocol (VCMP) — Low-latency, wire-efficient messaging
Encrypted Communication — TLS, RSA, AES-GCM built-in
Pluggable Eviction — LRU, LFU, TinyLFU, ARC, FIFO, and more
Minimal Config — Simple .env-style setup, no YAML or XML required
First-Class Developer SDKs — Official high-performance TCP clients, not REST wrappers:
- C#, Elixir, Go, Java, Kotlin, Node.js, PHP, Python, Ruby, Rust
Optional REST API — Lightweight HTTP access for environments where TCP isn't suitable
Fully Open-Source — Apache 2.0 license

Available Modules

VertexCache is modular — extend functionality only when needed:

AdminModule — Powerful admin commands: purge, metrics, config, reload, reset, session, shutdown, status
AlertModule — Webhook alerts for external monitoring; integrates with SmartModule
AuthModule — Secure, role-based client authentication with multi-tenant support
ClusterModule — Hot-standby clustering for high availability
MetricModule — Real-time performance metrics and cache insights
RateLimiterModule — Built-in traffic rate limiting
RestAPIModule — Optional REST API for simplified HTTP integration
SmartModule — Advanced features including indexing and future TTL optimization

Load Testing & Benchmarking

VertexBench — Official load testing suite for stress testing, QPS analysis, and real-world scenario validation
Ideal for tuning configurations, validating cluster performance, and measuring throughput under load.

Built for Real-World Complexity

Under the hood, VertexCache prioritizes interoperability, fault-tolerance, and security:

Binary Protocol Enforcement — VCMP ensures minimal overhead with predictable framing
Layered Encryption Stack — Combine transport security (TLS) with message-layer RSA or AES-GCM
Cluster-Ready by Design — Hot-standby, promotable secondaries with automatic or manual failover
Modular Activation — Deploy only what you need: SmartModule, AdminModule, Rate Limiting, Alerts
Cross-Language SDK Consistency — Identical protocol handling across all official TCP clients
Predictable Operational Behavior — Console-driven diagnostics, detailed metrics, and admin commands

All engineered to deliver fast, controlled caching — without sacrificing security or operational clarity.
