Implementing OLAP on Hadoop using Apache Kylin

Implementing OLAP on Hadoop using Apache Kylin

In this big data project, we will be performing an OLAP cube design using AdventureWorks database. The deliverable for this session will be to design a cube, build and implement it using Kylin, query the cube and even connect familiar tools (like Excel) with our new cube.

Project Description

Apache Kylin : Implementing OLAP on Hadoop platform

Perform OLAP on Hadoop big data platform has been a burden for a while, primarily due to high latency of queries. A different open source project like impala, presto and even apache hawq have tried to fix the problem with an MPP style of query execution architecture, but with an even larger dataset, performing query aggregation which is key to OLAP queries is still far from desirable.

Apache Kylin (kylin.apache.org) is a Distributed Analytics Engine that provides SQL interface and multidimensional analysis (OLAP) on the large dataset using MapReduce or Spark. This means that I can answer classical MDX questions in the Hadoop platform with a decent amount of latency.

In this big data project, we will be performing an OLAP cube design using the AdventureWorks dataset. The deliverable for this hadoop  be to design a cube, build and implement it using Kylin, query the cube and even connect familiar tools (like Excel) with our new cube.
