Indexes do not get recreated on module upgrade resulting in bad performance.
Update RAML Module Builder (RMB) from 29.2.1. to 29.2.2 to get this fix:
RMB-550 Index recreation on module upgrade.
All indexes will be recreated on module upgrade, this may take long. This is needed for
RMB-498 and other index changes of 29.2.0.
