Approaches to Content-Based Publish/Subscribe: Background

 

Content-based publish/subscribe removes limitations of the static topic-based flavor, but suffers from the dynamism it introduces.

In this section, we illustrate the latter difficulty by outlining the limitations of existing content-based schemes.
