StreamMine is a scalable middleware for massive real-time
data streaming. In this paper we present the BFSiena: a
communication substrate for the StreamMine. BFSiena is
a content-based, publish/subscribe communication system
which provides support for arbitrary predicate based mes-
saging in the acyclic peer to peer networks. BFSiena is a
low latency, high throughput communication system which
is well suited for the processing frameworks, like Stream-
Mine.
