Summary: Pre-deployed idle Task Managers Key: FLINK-32255 URL: https://issues.apache.org/jira/browse/FLINK-32255 Project: Flink Issue Type: New Feature Components: Kubernetes Operator Reporter: Christophe Bornet In the kubernetes operator, it would be nice to have the possibility to define a number of pre-deployed spare Task Managers. The operator would ensure that there are always a number of ready-to-be-used TMs that can accept new incoming jobs. The goal would be to reduce the startup time of jobs, especially in the session cluster mode. See for inspiration [https://www.decodable.co/blog/flink-deployments-at-decodable] -> Custom Flink Session Clusters for Preview Jobs: "To further reduce the preview response time, we also modified Flink to pre-deploy some idle TaskManagers. When a TaskManager is used, a new TaskManager is immediately created so there is always a pool of idle TaskManagers." -- This message was sent by Atlassian Jira (v8.20.10#820010)
