sstable2json and key ordering

Hi all, I'm having a lot of problems getting Lucandra to correctly handle numeric document fields. After examining the keys it has written to the CF, I believe it may be an issue of column ordering by bytes. After dumping the CF with the test data using sstable2json, the keys are in opposite o

Re: hector or pelops

I like both. Personally, I have switched from Hector to Pelops. Let me be clear, this is not because Hector is not a good client. Ran has done an excellent job with Hector, and it was what I initially used for my plugin. I preferred Pelops for my Datanucleus plugin since it requires slightly le

Hi Ran, I downloaded the git code, I think I have something up with my versioning, i have the latest build 0.6.0.14 of hector and the git download, i have a bunch of classes that do not appear to resolve, some of them are: * KeyspaceOperatorFactory ** ClusterFactory *Cluster Are these classes f

Re: Map Reduce support

The cassandra column family input format will go over a an entire column family sending a slice of a row into a mapper at a time. From there there's a lot you can do. As far as how you aggregate data together, I'd suggest experimenting with the latest version of Pig which thankfully supports the ne

RE: UUIDs whose alphanumeric order is the same as their chronological order

I think you have to use time in milliseconds + network card number (mac address) + a random number to genererate a uuid as microsoft .net framework. Iy guarantees uniqueness in a cluster Serdar - Thanks, Tatu! I'm going ahead with it.

Re: UUIDs whose alphanumeric order is the same as their chronological order

Thanks, Tatu! I'm going ahead with it. Now if something goes wrong I'll say: "But Tatu said..." (just kidding). I've replaced Random in the code above with SecureRandom, for that extra dose of randomness (my biggest worry was that Random self-seeds with System.currentTimeMillis(), and there is som
