Subject map/reduce on Cassandra
Date Mon, 25 Jan 2010 13:43:47 GMT
Multiple people have expressed an interest in 'hadoop integration' and  
'map/reduce functionality' within Cassandra. I'd like to get a feel  
for what that means to different people.

As a starting point for discussion, Jeff Hodges undertook a prototype  
effort last summer which was the subject of this thread: http://mail-archives.apache.org/mod_mbox/incubator-cassandra-dev/200907.mbox/%3Cf5f3a6290907240123y22f065edp1649f7c5c1add491@mail.gmail.com%3E

.

Jeff explicitly mentions data locality as one of the things that was  
out of scope for the prototype. What other features or characteristics  
would you expect to see in an implementation?

Thanks,
Phil
