This part sounds like a job for a DC-aware load-balancing policy in the driver.

Quick note from a driver dev's perspective:
Not knowing the problem you're trying to solve, I'm going to guess
cqlsh is a bad tool for this job. If you want to put the results of
CQL queries into a shell pipeline, a small custom script using a
driver is probably a better fit, and should be possible to write
without much effort.

They are different. In particular:
- 3.0.10 contains the features in versions 3.0.0, but with bugfixes.
It's the next in the series of 3.0.0, 3.0.1, 3.0.2, and so on to 3.0.9
and 3.0.10. Typically, 3.0.X releases don't add major features,
instead being smaller

I'm not sure what the state of documentation is for Change Data Capture.
The best docs may be the design document linked in the comments on the
ticket, which I think is current.

Have a look at CASSANDRA-8844, which is not merged to trunk yet, but will
be soon:

In addition, do I also have to upgrade to Java 7u60+ on C* servers as well.
Yes -- we observed C* nodes locking up when running under older
versions of the JDK.

Are prepared statements what you're looking for?

Jimmy,
What's the exact command that produced this trace? Are you saying that
the 16-second wait in your trace what times out in your CREATE TABLE
statements?
