What is C*?

Keep seeing refs to C*. I assume that C* == Cassandra? IMHO not a good ref to use what with C, C++, C#. A language called C* can't be far behind assuming it doesn't already exist. ;-) Jim C. signature.asc Description: OpenPGP digital signature

BTW, I agree with other posters that it seems like an awfully weird thing to do. Perhaps you just want to run a client in an OSGI environment? Jim C. On 07/22/2014 02:39 PM, jcllings wrote: > I can give you some tips. > > Figure out what Cassandra does when it starts up. Best way t

I can give you some tips. Figure out what Cassandra does when it starts up. Best way to do that is to read the startup script. Then all you have to do is convince the OSGI container to do what ever prep is done by the script. Trick to that is usually figuring out where to do it. For example if t

So It seems that: 1. There are indeed a few (3-4) mapping schemes. 2. CQL isn't very hard and represents a subset of (ANSI?) SQ92. Both of these are validated based on further research and list guidance. It appears that learning Cassandra from an application developers perspective essentially m

Correction, I mean vendor specific. Proprietary is OK so long as there aren't any lock-in tricks or they can be dodged easy. Jim C. On 07/22/2014 12:12 PM, jcllings wrote: > Does it have an annotation scheme or arrangement so I don't have to > put proprietary stuff in my Java? &

So I'm a Java application developer and I'm trying to find entry points for learning to work with Cassandra. I just finished reading "Cassandra: The Definitive Guide" which seems pretty out of date and while very informative as to the technology that Cassandra uses, was not very helpful from the pe
