counterpart to HBase's coprocessors.
hi community
I'm new to Cassandra and i'm wondering if there is a counterpart to HBase's
coprocessors in Cassandra. (basically i want to move some of the
computation to the server where data resides)
I did a little googling and found
https://issues.apache.org/jira/browse/CASSANDRA-1311 similar to what I'm
looking for.
However it seems not exactly the same thing. Then I found the article
http://www.javaworld.com/article/2140805/big-data/big-data-showdown-cassandra-vs-hbase.html
clearly claims that "Cassandra currently has no counterpart to HBase's
coprocessors."
Can I get some clear answer here? If it Cassandra currently has no
counterpart to HBase's coprocessors, is there any plan to implement a
framework that supports "move-computation-to-data"? I believe HBase was not
born with coprocessors:)
thanks ahead!

SOME lightweight processing is possible with UDFs / UDAs:
http://www.planetcassandra.org/blog/user-defined-functions-in-cassandra-3-0
/
They're not directly comparable to Hbase coprocessors, but they allow some
computation on the server.
