> Cqlsh provides context-sensitive tab-completion functionality, but it's only available when the readline library is available, and this is not the case where readline's GPL license proves problematic. [libedit|http://www.thrysoee.dk/editline/] is a common replacement, which would be available to Mac OS X-bundled Python users, and the Python readline module makes libedit almost a drop-in replacement.
> If possible, fallback to libedit functionality when providing tab completion.
