Zinc

Project Description

Zinc is a key-value store meant to be lightweight, easy-to-use and flexible.

It aims to provide a performant solution that runs efficiently on IoT devices and other systems such as servers with resource-constraints.

Roadmap

The following list of features is not set in stone. Things may change at any time, especially during early development.

Server

• Event loop to listen for client connections
  • Non-blocking, asynchronous
• Logging and telemetry
  • Formatting layer(s)
  • Storage layer
• Logger implementation using tracing + tracing-subscriber, etc.
• Maintain list of active connections
• Parse commands from clients
  • GET: retrieve values from store
  • SET: set new key-value pairs from store
  • DEL: removes key-value pairs from store
• Watch channel for hot-reloading
• Optimize for single-core, resource constrained systems
  • Support parallel processing through the use of an optional feature flag

Client

• Command line argument parser
• Logging and telemetry
  • tracing + tracing-subscriber

Common / Shared (Agent)

• Codec for bytes off the wire
  • encode method
  • decode method
• Encryption with authentication (AEAD and HMAC) ^{Note: independent of TLS}
  • Asymmetric encryption
  • Symmetric encryption
  • Key exchange algorithm
  • HMAC to verify data has not been tampered with
• Task-handling queue
  • Buffered channels (mpsc + spsc)
  • FIFO scheme
  • Optimized through use of proper concurrent data structures
