liyang updated KYLIN-1636:
--------------------------
Description:
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.
