Worker processes running on worker hosts are organized into a logical group and worker coordinators running on worker coordinator hosts coordinate tasks assigned to worker processes. A task store might hold a collection of tasks to be performed by the logical group. A lock database can be used for locking the logical group for coordination by one worker coordinator process at a time. A membership store contains mappings of worker processes to logical groups, and an assignment store indicates which tasks are assigned to which workers. The worker coordinator process has a scanner process to deal with unassigned tasks and deduplicating duplicate assignments. If a worker coordinator does not see enough worker processes, it can instantiate more. If a worker process does not see a worker coordinator, it can instantiate one."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contention and selection of controlling work coordinator in a distributed computing environment","description":"A distributed work processing system for processing computational tasks is scalable and fault-tolerant without requiring centralized control.
