WolfScale

Lightweight database replication and clustering tools for MariaDB and MySQL.

Pitch

WolfScale is a suite of tools designed for seamless database replication, clustering, and load balancing, providing a robust, high-availability solution for MariaDB and MySQL. With automatic leader election and WAL-based replication, it ensures strong consistency and ease of use, streamlining server infrastructure management.

Description

WolfScale is a powerful tool designed for creating resilient clustered server infrastructure. Originally developed as a database replication utility, it has evolved into a comprehensive suite of server clustering utilities, all encapsulated within a single, easy-to-setup Rust binary. The suite includes several key tools:

Tool	Description	Status
WolfStack	A management dashboard for servers, VMs, and containers with integration for Proxmox	✅ Available
WolfScale	Provides MariaDB/MySQL replication, clustering, and load balancing for high availability	✅ Available
WolfDisk	A distributed filesystem that allows for disk sharing and replication across networks	✅ Available
WolfNet	Enables secure private networking between machines over the internet	✅ Available

WolfScale – Database Replication

WolfScale delivers high-performance replication for MariaDB and MySQL databases, featuring:

Automatic Leader Election: Ensures consistent failover with a single leader model, allowing for easier management and reducing write conflicts.
WAL-Based Replication: Guarantees strong data consistency and allows for safe node rejoining.
Transparent MySQL-Compatible Proxy: Facilitates operation without necessitating changes to existing applications.

Key Features of WolfScale

Feature	Benefit
Sub-Millisecond Replication	Faster push-based replication compared to standard solutions.
Zero Write Conflicts	The single-leader model prevents certification failures.
Predictable Failover	Consistent handling of leadership based on the lowest node ID.
Zero-Config Discovery	Automatic node detection via UDP broadcast.
Built-in Load Balancer	Smooth distribution of database connections across cluster nodes.
Single Binary	Simplified installation with no dependencies.

Performance Comparison

WolfScale stands out with its industry-leading replication lag:

System	Typical Replication Lag
MySQL Async	100ms - seconds
MySQL Semi-Sync	10-50ms
MariaDB Galera	10-20ms
WolfScale	<1ms

Setup and Commands

WolfScale supports straightforward installation and maintenance.

Example command to set up:

curl -sSL https://raw.githubusercontent.com/wolfsoftwaresystemsltd/WolfScale/main/setup.sh | bash

Administration can be carried out using the following commands:

wolfctl list servers                # View cluster status
wolfctl stats                       # Monitor live throughput
wolfctl migrate --from 10.0.10.111:8080 # Migrate data to a new node
wolfctl reset --force               # Reset WAL and state (DESTRUCTIVE)

Additional Tools

WolfDisk – Distributed Filesystem

WolfDisk simplifies disk sharing and replication across networks, allowing servers to mount shared directories with automatic synchronization. Key benefits include:

FUSE-Based Architecture: Compatible with any application as it mounts like a standard filesystem.
Leader-Follower Model: Ensures strong data consistency.
Client Mode: Access shared drives without local storage requirements.

Example setup command:

curl -sSL https://raw.githubusercontent.com/wolfsoftwaresystemsltd/WolfScale/main/wolfdisk/setup.sh | bash

WolfNet – Private Networking

WolfNet establishes secure and encrypted networking between machines via the internet, making them interconnected as if on the same local network.

Key features include:

WireGuard-Class Crypto: Ensures secure communication through modern encryption protocols.
Mesh Networking: Allows for direct communication between nodes, enhancing resilience.

Quick installation command:

curl -sSL https://raw.githubusercontent.com/wolfsoftwaresystemsltd/WolfScale/main/wolfnet/setup.sh | sudo bash

Each tool within the WolfScale ecosystem is designed for seamless integration, ensuring a robust infrastructure to support modern applications. Whether managing databases, shared file systems, or secure networking, WolfScale offers a reliable, high-performance solution for server clustering needs.
