My belief as to the reason why you are unable to find design documents
which explicate the design principles behind Apache Cassandra is that
neither exist.

I continue to be a firm believer that a documented set of design principles
we all agree are "Cassandric" would be very helpful in cases where we need
to evaluate whether proposed patches are "Cassandric" enough to merge.

This, and people who have done the same and combined it with following JIRA
for regressions/bugfixes, are the path to the most accurate understanding
of how any given release of Cassandra works.
