Kiwi is a Redis-compatible key-value database built in Rust, leveraging RocksDB for storage and the Raft consensus algorithm to achieve strong consistency, high performance, and scalability.

• Uses RocksDB as the backend persistent storage.
• Highly compatible with the Redis protocol.
• Supports performance benchmarking using Redis.
• Planned modular support, allowing developers to customize extensions.
• Provides high-performance request handling capabilities.

• Operating System: Linux, macOS, FreeBSD, windows
• Rust toolchain

Please ensure that the Rust toolchain is installed, which can be done using rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Kiwi uses a Redis-style configuration file located at src/conf/kiwi.conf. Key configuration options:

• Port: Default is 7379 (configurable via port setting, Redis-compatible variant of 6379)
• Memory: Maximum memory usage (supports units: B, KB, MB, GB, TB)
• RocksDB settings: Various tuning parameters for the storage engine

Example configuration:

# Server port
port 7379

# Maximum memory
memory 1GB

# RocksDB configuration
rocksdb-max-background-jobs 4
rocksdb-write-buffer-size 67108864

For a complete list of configuration options, see src/conf/kiwi.conf.

Important: If you are upgrading from a version that used port 9221, note that the default port has changed to 7379. Please update:

• Client connection strings
• Firewall rules
• Container port mappings

Port 7379 was chosen to indicate Redis compatibility while avoiding conflicts with the standard Redis port (6379).

See CHANGELOG.md for detailed migration instructions.

• Support most Redis commands
• Add support for cluster mode
• Extend command support and optimize command execution efficiency
• Enhance modular extension features and provide examples
• Improve development documentation and user guides
