Highly-available Distributed Fault-tolerant Runtime

Untitled Database

Bastion is a highly-available, fault-tolerant runtime system with dynamic, dispatch-oriented, lightweight process model. It supplies actor-model-like concurrency with a lightweight process implementation and utilizes all of the system resources efficiently guaranteeing of at-most-once message delivery.

Usage

Bastion comes with a default one-for-one strategy root supervisor. You can use this to launch automatically supervised tasks.

Features

• Message-based communication makes this project a lean mesh of actor system.
  • Without web servers, weird shenanigans, forced trait implementations, and static dispatch.
• Runtime fault-tolerance makes it a good candidate for distributed systems.
  • If you want the smell of Erlang and the powerful aspects of Rust. That's it!
• Completely asynchronous runtime with NUMA-aware and cache-affine SMP executor.
  • Exploiting hardware locality wherever it is possible. It is designed for servers.
• Supervision system makes it easy to manage lifecycles.
  • Kill your application in certain condition or restart you subprocesses whenever a certain condition is met.
• Automatic member discovery, cluster formation and custom message passing between cluster members.
  • Using zeroconf or not, launch your bastion cluster from everywhere, with a single actor block.
• Proactive IO system which doesn't depend on anything other than futures.
  • Bastion's proactive IO has scatter/gather operations, io_uring support and much more...

Guarantees

• At most once delivery for all messages.
• Completely asynchronous system design.
• Asynchronous program boundaries with fort.
• Dynamic supervision of supervisors (adding a subtree later during the execution)
