------------------------------
Resolution: Duplicate
> 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
> Priority: Major
>
> 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."
