  == Simple time-series with roll-ups ==
  [[https://www.cloudkick.com/blog/2010/mar/02/4_months_with_cassandra/|Cloudkick]] implements
time-series down at the second-level with roll-ups.
  
- == An implementation of some DBMS rules written in python using pycassa
+ == An implementation of some DBMS rules written in python using pycassa ==
  We have created a DBMS layer that handles references to other columnfamilys (foreign keys),
Automatic reverse linking. required fields in columnfamilys and datatypes (long and datetime).
It wraps the get, get_range, insert, remove funtions of pycassas columnfamilys. At this time
it is limited to: on delete cascade and positive long numbers but this could change if there
is enough interest. It suits our project.
