BlinkDB: Queries with Bounded Errors and Bounded Response Times on Very Large Data
Queries with Bounded Errors and Bounded Response Times on Very Large Data BlinkDB is a massively parallel, approximate query engine for running interactive SQL queries on large volumes of data. It allows users to trade-off query accuracy for response time, enabling interactive queries over massive data by running queries on data samples and presenting results annotated with meaningful error bars.
