[teiid-dev] Fwd: [teiid-designer-dev] Connection Factories

[John Doyle]

Sorry Ramesh, I seem to have ignored this email.

Ken and I discussed this today.  I don't think there should be a ConnectionProfile for each source.  We could create profiles for each of the source we support, but I think there are two strong reasons not to.

1.  The ConnectionProfile for non-JDBC sources would only be usable by our importers.  For example, were I to create implement the DTP connection framework for Salesforce, I could modify the importer to the resulting ConnectionProfile.  But to have the rest of the DTP framework use the ConnectionProfile I would have to implement the getting of the metadata for DTP, and the mapping of the query API to DTP, etc.  It's a lot of work with no real value for us, and if we didn't do 'all' the work, it would be confusing for a knowledgeable user of DTP.

2.  Some of import sources don't have a connection.  XML to Relational and SOAP relational don't have to get their metadata from a 'connection' at all.  As often as not the metadata comes from a file on disk, and the connector points elsewhere.

This doesn't mean that the importer or some other action can't produce the info needed for the ~ds.xml.
