>
> This task aims to support spark codegen instructions (for all templates) over
> multiple RDD inputs if not all side inputs fit into the local and remote
> broadcast memory budgets. In detail, this might entail either (1) generating
> custom RDD operations and functions for various combinations of input RDDs,
> or (2) a generalization of the related spark instructions regarding the input
> RDD construction and a generic function signature.
