How to prevent data loss when deploying new MDM data model?

Hi together,

 

we are working with Talend MDM (6.5.1, commercial edition) with MySQL DB and are about to use the system in production.  In many cases during our development we experience that

  • just renaming an attribute in a MDM Object of with the data model
  • or adding an attribute to a MDM Object

forces us to recreate tables in MDM when deploying the new model.  In such cases it often even results in recreating about 80% of all tables even if the added/renamed attribute has nothing to do with other tables (no a foreign key attribute, etc.)

 

Who knows the right way to handle this?  

How do we avoid best to create tables?

How do we keep the history (update-reports) ?

 

With the current status we cannot risk to go into production.

 

Thanks for good recommendations!

Carsten
