Solid Queue 1.6.0 now supports fiber workers
摘要
Solid Queue 1.6.0 版本新增了 fiber worker 执行模式，允许在单个 fiber reactor 线程上运行多个任务，替代原先的线程池方式。配置时只需指定 fiber 数量而非线程数，但需要依赖 Async 库并启用 Rails 的 fiber isolation。该模式对 I / O 密集型工作负载（如 LLM 调用）特别有用。版本还包含其他修复和文档更新。
荐读理由
如果你在 Rails 项目中用 Solid Queue 处理 LLM 调用等 I/O 密集任务，可直接按说明配置 fiber 模式替代线程池，降低资源占用并提升并发效率。同时确认了该功能已正式发布，可纳入技术选型考量。
原文
A long-awaited feature thanks to @crmne on this release: instead of using a thread pool to run jobs in multiple threads per works, you can now use fibers on a single fiber reactor thread. To use this, you just need to specify the number of fibers instead of the number of threads in your worker configuration, like this:
workers:
- queues: "api*"
fibers: 100
polling_interval: 0.05
It uses Async under the hood, so you need to have that as a dependency for it to work. Also, you need to be using fiber isolation in Rails (config.active_support.isolation_level`` = :fiber).
This can be very useful for I/O-bound workloads, such as those involving LLM calls.
