Subject [jira] [Commented] (KYLIN-3501) Cube Data Exporter & Importer
Date Thu, 16 Aug 2018 03:55:00 GMT

Temple Zhou commented on KYLIN-3501:
------------------------------------

I know, but metastore.sh will backup all of the metadata, maybe too large. :( And it will
not backup the related hive table.

>             Project: Kylin
>          Issue Type: Wish
>          Components: Tools, Build and Test
>    Affects Versions: v2.1.0, v2.2.0, v2.3.0, v2.3.1, v2.4.0
>            Reporter: Temple Zhou
>            Priority: Major

> I think the performance problems is inevitable. So, I often migrate the cube from PROD
ENV to DEV ENV for performance tunning.
> My steps:
> 1. find the related metadata of the cube and export the metadata;
> 2. find the related hive table and export the table data;
> 3. import the cube metadata and load the hive table data
> 4. build the cube
> How about integrating the steps into a tool?
