> 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.
