Hi,
I want to increase the replication level in one of our datacenters from 1
to 2. This DC is live, so thought I'd do the right thing and email users,
instead of cowboying it.
It is a small DC with just 3 nodes, tonnes of space and quite strict
latency requirements. We are running 1.2.4 with

Hi guys,
I've read here [1] that you can make a deletion mutation for the future.
That mechanism operates as a schedule for deletions according to the
stackoverflow post. But, I've been having problems to make it work
Richard,
That's exactly what is happening with my row, but not what I was trying to
do. It seems that I misunderstood the stackoverflow post. I was trying to
schedule a delete for an entire row, is using ttl for columns the only way?
Thanks for the reply.

I am trying to understand the best procedure for adding new nodes. The one
that I see most often online seems to have a hole where there is a low
probability of permanently losing data. I want to understand what I am missing
in my understanding.
Let's say I have a 3 node cluster (node A,B,C)
Patricia,
Thanks for the info. So are you saying that the *whole* data is being
written on disk in the commit log, not just some sort of a summary/digest?
I'm writing 10MB objects and I'm noticing high latency (250 milliseconds
even with ANY consistency), so I guess that explains my high delays?
Everything is written to the commit log. In the case of a crash, cassandra
recovers by replaying the log.

Thanks/Shukran, Jon! :)
Wouldn't this make Writes disk-bound then? I think the documentation may
have been a bit misleading then Insert-heavy workloads will actually be
CPU-bound in Cassandra before being memory-bound?

Hi,
What's the difference between: rpc_send_buff_size_in_bytes and
internode_send_buff_size_in_bytes?
I need to set my TCP socket buffer size (for both transmit/receive) to a
given value and I wasn't sure of the relation between these two
configurations. Is there any recommendation? Do they have
Interesting... I guess you have to add one node at a time and run repair on
it.

I think the former is for client communication to the nodes and the latter
for communication between nodes themselves as evident by the name of the
property. Please feel free to correct me if I am wrong.

Would cassandra be a good choice for creating a funnel analytics type
product similar to mixpanel?
e.g. You create a set of events and store them in cassandra for things
like:
event#1 user visited product page
event#2 user added product to shopping cart
event#3 user clicked on checkout page
12 matches
