Subject RE: Is anyone using version 0.7 schema update API
Date Sun, 11 Jul 2010 22:32:27 GMT
My work for Cassandra 0.7 just started, which ensures existing API working
for 0.7. Supporting new features, like creating KeySpace and ColumnFamily,
will be added once the existing functionality tested.


You may follow changes on

Hi Dop,


Do you have any code on dynamically creating KeySpace and ColumnFamily.
Currently I was all but creating a new client to do that which seems to be
the wrong way.

If you have something that works that will put me on the right track I hope.

Something like:

1.       New Clock class instead of timestamp: this may be trivia, but it
takes some time to change

2.       Moving key space out of the API

3.       Key changed from string to byte

4.       Some API change, like get_count


I'm still exploring the changes since I'm working on a Java client for
Cassandra. There should be longer list than what I have discovered.


But, 0.7 is really good. I love the one can dynamically create Key Space and
Column Family. Also, I love the key to be a byte array instead of string. 


Enjoy the migrating. J

I want to move on to 0.7 using this API rather than storage-conf.xml

Any info that you can advise on how you used it would be much appreciated.
