Sandia National Labs and Kitware are in the midst of making it
possible to store and process very large graphs in distributed memory
using vtkGraph and the Parallel Boost Graph Library. Some of this is
currently in VTK, but it is not yet incorporated into ParaView. Your
other choice which may work for you is to use vtkPolyData with line
cells, since some of the operations you are talking about exist in
ParaView for polygonal geometry, although I don't know the exact
sequence of filters you would need for your use case. ParaView also
has the notion of multi-block data sets which can group assoicated
data sets into one object.
