> Is this a bug at teiid?
Probably. Is the index function based and/or what is the purpose of the hidden column? We should more than likely just not import indexes like this and log why.
Thanks for your quick response. We are not falimar with that database design. We just try to consume that database and to import the indexes for Cardinality information to improve the vdb performance. I agreed with you that teiid should not input those indexes to the hidden columns and log the resaon. I will open a teiid issue.
