Hello,
I've recently undertook a study into Cassandra internals. One of the reasons was because the available documentation, such as pages like this (http://wiki.apache.org/cassandra/ArchitectureInternals ) weren't very complete. One of the outcomes of the study was a blog post about C* top-level packages (talking about Java here). If people think it's a useful overview, I could adapt that content to be put on the wiki so other people can find it. If it's not a good fit, no problem (not trying to be pushy here). The blog post is this one http://timefork.com/blog/apache-cassandra-internals . Regardless of whether it goes into the wiki or not, if someone has corrections or is otherwise opinionated, I'm happy to hear him out. Daniel
