Install
The v2.0.0 beta requires a refresh install at the moment. It cannot be upgraded from v1.6.0 due to the incompatible metadata. However the underlying cube is backward compatible. We are working on an upgrade tool to transform the metadata, so that a smooth upgrade will be possible.
Run TPC-H Benchmark
Steps to run TPC-H benchmark on Apache Kylin can be found here: https://github.com/Kyligence/kylin-tpch
Spark Cubing Engine
Apache Kylin v2.0.0 introduced a new cubing engine based on Apache Spark that can be selected to replace the original MR engine. Initial tests showed that the spark engine could cut the build time to 50% in most cases.
To enable the Spark cubing engine, check this tutorial.
Great thanks to everyone who contributed!
