Hi all, first of all, I have read the Cassandra Hardware requirements page on Cassandra wiki: http://wiki.apache.org/cassandra/CassandraHardware .
I am currently in a simple project that, fetches data from a message broker. That data can be thought as logging data, about a system user usage. I need to have a background process to read the data from the message broker and persist it somewhere. The data I want to persist, could be stored in a single SQL table, however there is no data to relate, therefor, I thought I would not need a Relational database approach. I have been trying Cassandra, and have write the background process to store all my data, in 3 column families, ordered by timeuuid, that could be handy for some analysis:). I have read some articles/case studies and all of them talk about the need to support thousands of writes per second. Well in my case I would only need about 10 writes per second in the worst case scenario. Do I really need to have 16 GB RAM servers running Cassandra? I have two servers, with 4 cpu (2 cores each cpu). And about 4 GB of RAM each. I was planing on deploying a cassandra node on each, and an apache web server, to host a simple web application, that will query my cassandra cluster and use the data stored to present graphs and tables (statistical information). Do you think I may get into trouble with this design choice in the future? Best Regards, Rui Silva
