#### Queries with Bounded Errors and Bounded Response Times on Very Large Data

BlinkDB is a large-scale data warehouse system built on Shark and Spark and is designed to be

compatible with Apache Hive. It can answer HiveQL queries up to 200-300 times faster than Hive

by executing them on user-specified samples of data and providing approximate answers that are

augmented with meaningful error bars. BlinkDB 0.1.0 is an alpha developer release that supports

creating/deleting samples on any input table and/or materialized view and executing approximate

HiveQL queries with those aggregates that have statistical closed forms (i.e., AVG, SUM, COUNT,

VAR and STDEV).

#### BlinkDB requires:

* Scala 2.10.x

* Spark 0.9.x
