How many keyspaces can you reasonably have? We have around 500 customers
and expect that to double end of year. We're looking into C* and wondering
if it makes sense for a separate KS per customer?
If we have 1000 customers, so one KS per customer is 1000 keyspaces. Is
that something C* can handle
You will get an error back . Also use RF:3 for the high availability in one
DC.

Hi - I have 2 data centres (DC1 and DC2) and I have local_quorum set as the CL
for reads. Say there is a RF factor = 2. (so 2 copies each in DC).
If both nodes wh
I haven't done any performance testing with Cassandra 1.2, I was only

I am aware of no benchmark that shows the binary driver to be faster then
thrift. Yes. Theoretically a driver that with multiplex *should be* faster
in *some* cases. However I have never seen any evidence to back up this
theory anecdotal or otherwise.

Hi Aaron, Rob,
Thank you for your responses. Sorry about the delay in getting back to
you. To answer your questions:

The binary protocol is able to multiplex multiple requests using a single
connection, which can lead to much better performance (similar to HTTP vs
SPDY). This is without comparing the performance of thrift vs binary
protocol, which I assume the binary protocol would be faster since it is

Hey Shamim,
Why do you say that Java-Driver has better performance over Hector or
Astyanax? Is there any reasons for this?
Thanks.

Hello,
Last night one of our nodes froze and the server had to be rebooted. After it
came up, the node joined the ring and everything looked normal.
However, this morning there seem to be some inconsistencies in the data (e.g.
some nodes don't have a given record or have a different version of
Hi,
Astyanax is just a refactoring of Hector and implements a few common
cassandra use cases. Very easy to use api. In Astyanax you will found all the
functions from hector. For better performance you can also check datastax java
driver https://github.com/datastax/java-driver.
