> Views: Make view extraction a background task.
> ----------------------------------------------
>
> Key: AMBARI-7158
> URL: https://issues.apache.org/jira/browse/AMBARI-7158
> Project: Ambari
> Issue Type: Task
> Reporter: Tom Beerbower
> Assignee: Tom Beerbower
> Fix For: 1.7.0
>
>
> The first time that a view is deployed, the contents of the archive are
> extracted to the file system.
> Currently view extraction can slow the initial startup of Ambari
> significantly.
> It would be ideal if we could start the view extraction process as background
> tasks while Ambari startup is allowed to proceed. This means that an API user
> may be able to make requests for view APIs before the view has finished
> deploying. We could add a state field to view with the following possible
> values ...
> PENDING - the view archive has been discovered but the extraction process
> has not yet started.
> INSTALLING - the view archive is being extracted.
> INSTALLED - the view archive is fully extracted and the view is ready to
> use.
> Until a view is fully installed the API user will not see instances for that
> view.
