Subject Hbase fast access
Date Fri, 21 Oct 2016 08:43:38 GMT

This is a general question.

Is Hbase fast because Hbase uses Hash tables and provides random access,
and it stores the data in indexed HDFS files for faster lookups.

Say compared to Spark that is basically a SQL layer relying on different
engines (mr, Tez, Spark) to execute the code (although it has Cost Base
Optimizer), how Hbase fares, beyond relying on these engines
