They are really in mebibytes (MiB). In the upcoming release of Cassandra,
the configuration is getting standardised to KiB, MiB, etc, to remove
ambiguity (CASSANDRA-15234 [1]). For more info, see Ekaterina
Dimitrova's blog post [2]. Cheers!

SSDs definitely help. I think JBOD works correctly in newer versions
(CASSANDRA-6696 that separates data by token, so you dont have to rebuild
the whole node, not sure off the top of my head if there's followup
tickets).
10GB probably more useful if you use vnodes than single tokens (likely to

The term "commodity hardware" is not very useful, though the
averageserver-class machine bought in 2017 can work.
Netflix found that SSD helped greatly with compactions in production.Generally
servers use 10 GB networking in 20
Yup, unframed transport was removed in 0.8.beta 2.
I'll fix the comments, thanks.

When I write client code in Java, using Hector, I don't specify a

All nodes should have the correct configuration files. With the only difference

I've done this before with puppet, but any sort of mainstream
configuration management system should work. There will be some
management overhead in making sure any token changes make it back into
the right server-specific template, but otherwise it's straight
forward.

You can specify the location of cassandra.yaml with a url so you can keep
your configs in one (redundant place) like S3 or generate them on the fly in
a http service...

Funny you should mention that. I just put my half-baked solution to
this problem on github today.
https://github.com/gdusbabek/cassandra-maker. It generates
cassandra.yaml files (and entire config directories too) that are
based on the svn defaults. It should be easy to customize it to fit

Thanks for the explanation, I'll see if I can merge that into the http://wiki.apache.org/cassandra/StorageConfigurationandhttp://wiki.apache.org/cassandra/StorageConfiguration_0.7pagesAaronOn 24 Aug, 2010,at 12:42 AM, Sylvain Lebresne wrote:The cassandra.yaml holds general configuration of cassand
The cassandra.yaml holds general configuration of cassandra and the
schema definitions.
As of 0.7, the schema definition are not need anymore in this file as
schema can be defined
programatically. Those definition are are ignored by any node that
already have schema loaded
(hence the warning). But
Also, when you are testing trunk, please remember to read NEWS.txt, as things
change frequently.
