Hi Alexandru,

   We @ EvidentSoftware (http://www.evidentsoftware.com/) have a monitoring
solution  that is storing timeseries information in Cassandra and also
neo4j. Check this blogpost
http://www.evidentsoftware.com/evident-clearstone-5-implements-cassandra-and-neo4j-as-an-elastic-data-store/.
Can you share more details about your use case, so we can give you some
guidance.



Prasanna

Hello,

I'm currently doing my masters project. I need to store lots of time series
data of any type (String, int, booleans, arrays of the previous) with a high
writing rate(20MBytes/sec -> 170TBytes/year - note not running continuously)
but less strict read requirements. This is monitoring data from a vast
distributed network. The queries will be something like: give me this data
between Time1 and Time2.

The hardware that I have available is between 2 and 5 hosts.

Questions:

                   Should I use Cassandra?

                   Suggestions of how to structure the data? (I read
Cloudkick's blog
https://www.cloudkick.com/blog/2010/mar/02/4_months_with_cassandra/ but I
found that it doesn't give too much detail)



Any help is much appreciated,

Alex
