Hi,
Cassandra's documentation has several recommendations for moving the commit
log directory to a dedicated disk, separated from the sstables disk(s).
However, I couldn't find much information on what would be good practices
regarding this dedicated commit log disk and I'm wondering how to config
Hi,
I'm trying to understand how seed nodes are working, when and how do they
play a part in a Cassandra cluster, and how they should be managed and
propagated to other nodes.
I have a cluster of 6 Cassandra nodes (let's call them #1 to #6), on which
node #1 and #2 are seeds. All the configuratio

Hi Jeff,
thanks for answering to most of my points!

Hi,
we are running an application which produces every night a batch with

it is never modified (nor updates nor deletes), we just keep producing

I added a new node to my cluster but in a new datacenter. After updating
the keyspace replication factor values (using the
NetworkTopologyStrategy strategy), I'm now running a "nodetool rebuild"
on the new node.

It seems like the Datastax Python library from

not exactly clear how I would use this library along with Twisted. The
