I keep one connection per bolt and for now it works just fine with many
bolts. I would also be interested in hearing from someone else and share
experiences.

For now, I open the connection in the method prepare (and close it in
cleanup), but to be completely honest, I'm not 100% sure if this is the
best approach.

cheers,
Pablo.
