> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.1
> Reporter: Valentin Kulichenko
> Assignee: Dmitry Karachentsev
> Priority: Critical
> Fix For: 2.2

>
> {{IgniteCache#loadCache}} method broadcasts an internal task under the hood.
> If one of the jobs are local (i.e. if {{loadCache}} is invoked on server
> node), this job is executed in a caller thread, potentially *before all or
> some remote requests are sent*. Since data loading is generally long running
> process, its duration doubles in this scenario.
> Possible solution is to check the list of nodes before task execution, and if
> local node is there, execute on remote nodes first, and only then submit to
> local node. This way we make sure that remote nodes never wait for the local
> node.
