FRAMED TRANSPORT AND BUFFERED TRANSPORT
There are two choices for which transport type you want to use to connect to Cassandra: Framed Trans-
port and Buffered Transport. Framed Transport was added to Thrift in order to support asynchronous
servers. There's not necessarily a performance difference between the two, but your choice of client lan-
guage might dictate which one you need to enable. For example, Twisted Python requires using Framed
Transport, whereas Haskell, Ocaml, Cocoa, and Smalltalk (as of this writing) do not support Framed
Transport.
Because you need to enable this on the Cassandra server, the console asks you to indicate which one
you're using.
Once you've connected to a Cassandra server, the web console reads its configuration informa-
tion and brings you to a screen to start interacting with Cassandra.
Figure 8-1
shows the configuration screen for the console itself.
Figure 8-2
shows a screenshot
of the keyspace and column family configuration information that the web console lets you view.
You can see here that I have four keyspaces. Keyspace1 has been selected to show the column
family definitions; the others are system, Test, and Twitter. Using this screen, you can add a
column family to the keyspace, rename a keyspace, drop a keyspace entirely, or create a new key-
space.
