problem

If the materialised view was missing for a task (automatically deleted after some days) and some tried to make a translator package re-import it might happen that due the missing mat view the segments could not be re-imported.

reproduction

• drop the mat view
• Add a sleep to the mat view create command - since its triggered by the getAction and probably other requests in parallel so that the wrong behaviour can not be reproduced

solution

• check and create mat view first before usage at the specific code place
• fix logging so that segment exceptions can be traced on re-import
