Luke Han commented on KYLIN-700:
--------------------------------
>
>
> Open question:
> 1. How to copy between different cluster for large cube?
> \
>
no experience on this before, do we need to consult our hadoop support
team?
>
>
> 2. Move or copy? Move will disable access from source, copy will ask more
> additional storage.
>
To support rollback, it'd be best to copy rather than move.
To control storage consumption we can delete the original cube later.

> Cube Release Tool

> Key: KYLIN-700
> URL: https://issues.apache.org/jira/browse/KYLIN-700
> Project: Kylin
> Issue Type: New Feature
> Components: Tools, Build and Test
> Reporter: Luke Han
> Assignee: hongbin ma
>
> In real case, there's always different environment for user to develop, test
> and serve as production.
> To avoid rebuild same cubes on different environment, release
> verified/certified cubes from Dev/QA to Prod is more efficient way, and, this
> will support almost zero downtime when cube's data model changed (build first
> on QA and release to Prod)
> This tool will enable user to "release" cubes from one environment to another
> one:
> 1. Shell script is good enough so far
> 2. Service/Web GUI is nice to have
> 3. Only project admin/system admin could do this movement
> 4. Parameters:
> Source: Env(Host?)/Project/Cube
> Target: Env(Host?)/Project/Cube
> The target project/cube could be different name than source's
> 5. Support move metadata only and both metadata & data
> 6. Support rollback, for example, when the moving failed, the target cube
> should not be effected (keep as previous)
> 7. Log all actions for tracking
> Open question:
> 1. How to copy between different cluster for large cube?
> 2. Move or copy? Move will disable access from source, copy will ask more
> additional storage.
> Please leave your comments here.
> Thanks.
