hadoop - Hadoop Hypercube

Question

Hey, i am starting a hadoop based hypercube with a flexible number of dimensions. Does anybody know any existing approaches for this?

I just found PigOLAPSketch, but there is no code to use it.

Another approach is Zohmg from lastfm, which uses hbase, but seems to be very dead.

I think i will start a pig solution, maybe you have some advices?

Answer 1

这将非常酷/有用。OpenTSDB 是一个 HBase 时间序列数据库，看起来可能很有趣，它们有一种巧妙的二级索引方法。

Answer 2

您还可以查看基于 gpu 的数据库https://www.kinetica.com/ 但这不是开源的，需要单独的设备并将数据从 Hadoop 移动到 Kinetica 基础设施。
