Sorry about unclear naming scheme. I meant that if I want to index on a
few columns simultaneously,
I create a new column with catenated values of these.

Sorry to fork this topic, but in "composite indexes" do you mean as strings

SSD's definitely makes live simpler as you will get a lot less trouble with
impact from things like compactions.
Just beware that Cassandra expands data a lot due to storage overhead (for
small columns), replication and needed space for compactions and repairs.
It is well worth doing some rea
Plenty of comments in this thread already, and I agree with those saying
"it depends". From my experience, a cluster with 18 spindles total
could not match the performance and throughput of our primary
Oracle server which had 108 spindles. After we upgraded to SSD,
things have definitely changed f
Hi,
The hardware you choose depends a bit on your workload - writes vs
reads, amount of cacheable data, latency requirements, etc.. What
sort of workload do you expect?
See http://wiki.apache.org/cassandra/CassandraHardware for some general advice.
People typically have 8-24 GB RAM per node wit
Hello guys,
What is the type of profile of a cassandra server.
Are SSD an option ?
Does cassandra needs better CPU ou lots of memory ?
Are SATA II disks ok ?
I am making some tests, and i started evaluating the possible hardware.
If someone already has conclusions about it, please share :D
