How to retrieve the timestamp from cassandra?

It's not recommended to use column Cassandra timestamps directly in client code; ideally, you should add your own timestamps in whatever form is most appropriate to your schema. But if you really want to, it can be done through the thrift interface (and, by extension, certain libraries using the thrift interface).

For the pycassa case, you just need to add include_timestamp=True to the arguments for your .get() call. For the CQL, cqlsh, and cassandra-cli cases, I believe there's totally no way to get the timestamp, sorry.

Just ran across this thread, and found that the answer is out of date. CQL now exposes the internal timestamps using the writetime() function:

select key,columnfoo,writetime(columnfoo) from tablebar;
