Hi @IshanDindorkar,
It is not possible to work right now with a Pandas Dataframe and YARRRML.
However, for your pipeline with Impala I think it is much better solution to implement an Impala connector in Morph-KGC. That way you could use YARRRML with SQL queries and you woud significantly simplify your pipeline.

@arenas-guerrero-julian thanks for your quick answer. You are completely right, that would improve our pipeline. I assume that implementing that in Impala will take quite a while right?

I have to check but I think it would not take a lot. I can maybe take a look in the next weeks.
