Google's BigQuery API facilitates the querying of large data sets. Using Google's significant processing power, BigQuery uses SQL-like commands to query and manage data in append-only tables. Use this SDK to interface with the API using Java. See the project page for information on installing the Java client, access to the JavaDoc for BigQuery, and a sample API engine. Google's Java SDK is supported in the following environments: Java 5 or higher, Android 1.5, and Google App Engine.
Splice Machine prides itself on being the only transactional SQL-on-Hadoop database aimed at giving developers an easy-to-learn tool for managing big data in the enterprise. ProgrammableWeb spoke with Splice Machine's CEO Monte Zweben at the recent API World and Data Week conference in San Francisco - where they won a Top Innovator award - to discuss how API developers can access the best-of-both-worlds SQL and NoSQL database engine to return contextual and personalization data in realtime.
