Ippokratis Pandis (Cloudera)

The Cloudera Impala project is pioneering the next generation of Hadoop capabilities: the convergence of fast SQL queries with the capacity, scalability, and flexibility of a Hadoop cluster. With Impala, the academic and Hadoop communities now have an open-sourced codebase that helps query data stored in HDFS and Apache HBase in real time, using familiar SQL syntax. In contrast with other SQL-on-Hadoop initiatives, Impala’s operations are fast enough to do interactively on native Hadoop data rather than in long-running batch jobs.

This talk starts out with an overview of Impala from the user’s perspective, followed by a presentation of Impala’s architecture and implementation. It concludes with a summary of Impala’s benefits when compared with the available SQL-on-Hadoop alternatives.
