Hi, Is it possible for an adapter to leverage RexImpTable to handle calculations?
>From RexImpTable I can get an Implementor for a given operation in a RexCall, but then the implement method that would generate an expression, takes a RexToLixTranslator. The RexToLixTranslator has a private constructor, so I'm not sure how to get hold of one. I also couldn't find any supporting prior art in the various adapters in the code-base. Does my approach make sense, to want to use Calcite for handling calculations across projects, filters & join conditions? Context is that our database is a rule-engine that runs in-process - I want to pass it arbitrary functions that could potentially wrap Linq expressions, to implement a wider range of SQL backed by Calcite. Regards, Jon.
