   @0x6d686b you wrote about rows sorting in !cassandra

     @musicsense Ah, yes more or less. It's very different to relational DBs though.

   You know what I totally dislike in !cassandra? No WHERE statement, rows are NOT sorted … a lot more difficult to wrap my brain around it.

   And one step further with my !ruby #ramaze project with !cassandra db. Soon the !webdesign part will start. Looking forward! :-)

   Worked on my current !ruby #ramaze project with !cassandra as DB for a society. I like the ease of it.

     @0x6d686b Awesome, I really like #ramaze as a lightweight MVC.

     @nuclearsandwich hehe, @killerfox suggested it and I have to say it's very easy to use. Except my skills suck and I lack of know-how. ;-)

   Are the !cassandra rowkeys sorted? If yes how? Because some entries are missing with list calendar['2011-01-01':'2011-05-23']; Anyone?

    Just got a knot in the brain while using !ruby and !cassandra along with get_range … whatever you get back, it behaves … strange. :D

    Is it possible that the !cassandra cli is broken?

12. Mathias Hablützel Apache Cassandra

    I need to do an "auto-increment" like I knew it under ordinary SQL DBs. Anyone at !cassandra knows how? Or do I have a bad DB design?

      @0x6d686b try to use UUIDs instead of an incrementing number.

    James Anderson (github.com/lisp) is building software transactional memory (STM) in !Lisp on top of !RDF and !Cassandra. Cool stuff!

    Figuring out how to tune !Cassandra and the JVM for big iron (32+ GB RAM) to prevent 20-second GC pauses under heavy load... links welcome.

    Cons of !Cassandra for !RDF storage: count operations suck. Waiting to implement caching with atomic increment/decrement in Cassandra 0.7+.

16. Arto Bendiken Data on the web , Apache Cassandra

    Pros of !Cassandra for !RDF storage, aside from all the obvious: blazing write speeds don't deteriorate even after quarter billion triples.

    RDF.rb now has storage adapters for !Cassandra and MongoDB - soon to be the definitive Linked Data solution for !NoSQL projects?
