講題：Speed up Interactive Analytic Queries over Existing Big Data on Hadoop with Presto
Presto is a new open source distributed SQL query engine released by Facebook. It is used by Facebook and other companies for interactive queries against petabyte-scale big data. It features easy-to-use, easy-to-deploy and approaches the speed of commercial data warehouses. You can easily deploy Presto to access and query existing data sources such as Hive and Cassandra. This talk will introduce Presto and show how to install, deploy Presto on Hadoop cluster to speed up data access of existing Hive data.
