Subject Re: Apache MetaModel - an interesting future integration target
Date Thu, 01 Oct 2015 11:10:58 GMT
Hi Jacques,

I think we can best answer that together. I didn't yet dive into all the
details of Drill, but from a high level it seems that we could maybe
provide connectivity to a wide set of databases and file formats, which you
could leverage. The query syntax for all MetaModel connectors is exactly
the same, only the schema/table model may differ. But that means to me that
if you plug in one connector, you probably have them all. The main
complication as I see it is how to mediate the Drill queries to MetaModel
queries. Your query language seems to be richer than MetaModel's,
containing more functions and operators. So how can we best ensure that the
maximum amount of the query gets passed on to MetaModel, without passing on
stuff that MetaModel wouldn't support.

Best regards,
Kasper
