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! -- Regards, *Bin Mahone | 马洪宾* Apache Kylin: http://kylin.io Github: https://github.com/binmahone
Re: counterpart to HBase's coprocessors.
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.
