> Allow execution of optional tasks in exchange worker
> ----------------------------------------------------
>
> Key: IGNITE-4834
> URL: https://issues.apache.org/jira/browse/IGNITE-4834
> Project: Ignite
> Issue Type: Task
> Components: cache
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Fix For: 2.0
>
>
> Exchange worker is responsible for cache start/stop. With introduction of DD
> and hence dynamic updates of cache types and indexes, it is necessary to
> properly synchronize these operations wrt cache lifecycle.
> The most obvious way is to initiate these operations from within exchange
> worker thread. In this case concurrent cache start/stop will always be
> handled correctly.
> At the moment exhange manager is not ready for this. Need to perform some
> refactoring to allow for optional tasks to be executed from that thread.
