问题描述
我有一个Cassandra集群,其中有4个表和数据。
I have a Cassandra cluster with 4 table and data inside.
我想使用聚合函数(sum,max ...)在这里阅读这是不可能的:
http:// www .datastax.com / documentation / cql / 3.1 / cql / cql_reference / cql_function_r.html
I want to make request with aggregation function ( sum, max ...) but I've read here that it's impossible : http://www.datastax.com/documentation/cql/3.1/cql/cql_reference/cql_function_r.html
有一种方法可以使sum,average,group by,
Is there a way to make sum , average, group by, without buying the enterprise version, can I use presto , or other solutions?
感谢
