Err, find it *unrealistic*

Are there any plans or talks of adding SSL/encryption support between
Cassandra nodes? This would make setting up secure cross-country Cassandra
clusters much easier, without having to setup a secure overlay network.
MySQL supports this in it's replication.

Hi, my name is Larry and I am the Beverage Considerer for NUB Enterprises.
I am new to Coke and Digg, but I've already been reading Coke's nutrition
facts on the internet and even purchased a bottle the other day (it's
sitting in my office fridge right now). It looks like quite a promising
office
Joe,
(Disclaimer: I work here) Check out http://www.simplegeo.com, we're
building a horizontally scalable spatial database on top of Cassandra
along with geographic analytics, data provisioning, and hosting
services. Using us might be easier than hacking around in the weeds
with MongoDB.
Sorry f
"For various reasons I am required to deploy systems on Windows."
I don't think it would be difficult to argue the business case for running
Cassandra on Linux. It's still a young project and everybody in IRC and the
mailing list is running it on Linux. You should really re-think whatever
factor
In my opinion the #1 risk for corruption is user/client error with the
timestamps. Over time, Cassandra flushes data from memory to disks. After
it flushes to disk, Cassandra doesn't go back to delete or modify that data.
Because of this, deletes are performed by writing a "tombstone" to disk.

Using XFS as described here
http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1663
also makes it very easy to snapshot your cluster to S3.
We've had no real problems with EC2 and Cassandra, it's been great.

On EC2, it is common and recommended (
http://developer.amazonwebservices.com/connect/entry.jspa?categoryID=100&externalID=1663)
to use XFS's freeze/thaw functionality to create near-online snapshots of an
EBS volume for MySQL snapshots.
