RE: Hector samples -- where?

I am also interested in this.  It seems like adding multiple Cols into a CF or 
SuperCols would be very useful.  Like a dataload type capability?

Are there examples of inserting multiple cols into a CF anywhere?

The best examples are in KeyspaceTest but don't include all scenarios

Thanks All,

 

 I found it here:

 

http://code.google.com/p/cassandra-java-client/source/browse/trunk/src/test/java/org/yosemite/jcsadra/impl/KeySpaceTest.java?r=50

 

 I’m actually fairly new to OSS, but I wanted to really dig into the 
software here.  So far, so good.

RE: Thoughts on adding complex queries to Cassandra

2010-05-26 Thread Nicholas Sun
I'm very curious on this topic as well.  Mainly, I'd like to know is this
functionality handled through Map/Reduce HADOOP operations?

Subject: Thoughts on adding complex queries to Cassandra

 


Are there any thoughts on adding a more complex query to Cassandra?

At a high level what I'm wondering is: Would it be possible/desirable/in
keeping with the Cassandra plan, to add something like a javascript blob on
to a get range slice etc, that does some further filtering on the results
before returning them. The goal being to trade off some CPU on Cassandra for
network bandwidth.

Row Time range

2010-06-04 Thread Nicholas Sun
Is there a mechanism to select a time range within a row range query?  Is
this planned?  For example, return to me the last 10 post starting at 7:00pm
yesterday?
