红帽全球峰会5.5. Dynflow Tuning
Dynflow 是工作流管理系统和任务编排器，它是卫星插件，用于以顺序执行方式执行卫星的不同任务。当很多客户端在卫星中检查并运行多个任务时，Dynflow 会从添加的调优中取一些帮助，指定启动多少 executors。
有关与 Dynflow 相关的调整的更多信息，请参阅 https://satellite.example.com/foreman_tasks/sidekiq。
增加 Sidekiq 工作程序的数量
Satellite 包含一个名为 dynflow-sidekiq 的 Dynflow 服务，它执行由 Dynflow 调度的任务。Sidekiq 工作程序可以分组到不同的队列中，以确保某一类型的大量任务不会阻止其他类型的任务。
红帽建议增加 sidekiq worker 的数量，以扩展 Foreman 任务以实现批量并发任务，如多个内容视图发布和促销、内容同步和与胶囊服务器同步等。有两个可用选项：
- 您可以增加 worker 使用的线程数量(worker 的并发)。由于 Ruby 实现线程并发实现，这对超过五个的值的影响有限。
- 您可以增加推荐的 worker 数量。
流程
将 worker 数量从一个 worker 增加到三，同时剩余五个线程/并发：
satellite-installer --foreman-dynflow-worker-instances 3 # optionally, add --foreman-dynflow-worker-concurrency 5
# satellite-installer --foreman-dynflow-worker-instances 3 # optionally, add --foreman-dynflow-worker-concurrency 5Copy to Clipboard Copied! Toggle word wrap Toggle overflow 可选：检查是否有三个 worker 服务：
