Description of problem:
Require a quick start example for customer on how to setup extension properties on materialized view model .

As per the documentation [1]
in => Table 3.2. Extension Properties
There are few properties listed . 
eg. teiid_rel:MATVIEW_TTL  etc

Need step by step instruction on how to setup these properties for the materialized View model(not the dynamic vdb)



Is MED an option to achieve this per [2]? If yes need a step by step instruction  on how to set this up for the materialized View model.
