Macro Pipeline

The macro pipelines are defined by simply interconnecting multiple micro pipelines through a commonly used source/sink. The output of micro pipeline A is used as input to micro pipeline B.

Although the goal of SPQR is to provide a user-friendly interface for querying streams and defining new new streams by filtering or aggregating existing ones the definition of macro pipelines has to be carried out manually as there is no mapping from a DSL to a specification yet.
