> Benchmark scan speed on different storage

> Key: KYLIN-1636
> URL: https://issues.apache.org/jira/browse/KYLIN-1636
> Project: Kylin
> Issue Type: Improvement
> Reporter: liyang
>
> We want to better understand the scan speed of different storage. Namely
> HBase, Cassandra, Parquet, MemMappedFile etc.
> To be specific, we test reading 10 millions records with single thread. Each
> record is 5 dimensions of type int4, and 2 measures of type long8, totally
> ~50 bytes if include cuboid ID and other overhead.
