Hi there, My application is uses Cassandra to store abstracted sensor data from a sensor network in large building (up to 3000 sensors). For now I am starting one node in one floor of the building, for the future it will definitely be a cluster. Some of the sensors have up 16HZ sampling rate.
And now I want to make a decision if I have to focus on big RAM or large number of cores. greetings Ambes ________________________________________ From: Romain HARDOUIN [romain.hardo...@urssaf.fr] Sent: Friday, October 12, 2012 10:57 AM To: user@cassandra.apache.org Subject: Re: what is more important (RAM vs Cores) Hi, Sure it depends... but IMHO 6 GB is suboptimal for big data because it means 1,5 GB or 2 GB for Cassandra. Maybe you could elaborate your use case. You really want a one node cluster ? cheers, Romain wang liang <wla...@gmail.com> a écrit sur 12/10/2012 10:36:15 : > Hi, Hagos, > > I think it depends on your business case.
