Splice Machine promises SQL- and ACID-compliant RDBMS for analytics and transaction processing on a super-scalable, low-cost Hadoop platform.

Promising the best of both worlds, startup Splice Machine last week announced the latest stab at putting SQL on Hadoop, but this time it's a fully SQL-compliant and ACID-compliant relational database management system (RDBMS) on Hadoop that's not just for analytics.
"Splice Machine can replace Oracle, Microsoft SQL Server, IBM DB2, or MySQL, where those systems might hit the wall from a performance or cost perspective," said Monte Zweben, CEO of Splice Machine, in a phone interview with InformationWeek.
Hadoop provides the scale-out technology for Splice Machine, so it runs on scalable, commodity clusters. At the same time it's compatible with existing investments in SQL-based business intelligence software, ETL systems, and applications through an ODBC/JDBC driver.
Several databases have been ported to run on top of Hadoop, including Pivotal's Greenplum database (through HAWQ) and InfiniDB, but these are specialized databases designed for high-scale querying and analysis. Splice Machine, which marries the open-source Apache Derby Java-based database with Hadoop's HBase NoSQL database, touts RDBMS-speed transaction processing.
"Our unique differentiation is that we're the only [SQL-on-Hadoop option] that can support concurrent reads and writes in a transactional context with ACID compliance," says Zweben.
Splice Machine uses a concurrency control method called "snapshot isolation" in combination with HBase, which has ACID properties over updates in a single table. The Apache Derby SQL planner and optimizer have been extended to take advantage of Hadoop's parallel architecture, according to Zweben. As plans are executed on each node, they're spliced back together -- thus the name of the company.
"We started with two well established open-source stacks, Derby and Hadoop, and that's one of the reasons we can come to market so quickly," says Zweben. Splice Machine was founded in 2012.
With last week's introduction, Splice Machine entered public beta, but the company says it has 15 charter customers in industries including digital marketing, telecom, and high-tech. One of those customers is well known marketing services firm Harte Hanks, which has been testing Splice Machine since last summer.
Harte Hanks is poised to replace Oracle RAC in a campaign-management application that combines IBM Unica, IBM Cognos reporting, Ab Initio data-integration software, and Trillium data-cleansing technologies. All of the above are designed to run on or work with SQL RDBMSs, so moving the app onto Hadoop or

6 Tools to Protect Big DataMost IT teams have their conventional databases covered in terms of security and business continuity. But as we enter the era of big data, Hadoop, and NoSQL, protection schemes need to evolve. In fact, big data could drive the next big security strategy shift.
Big Data Brings Big Security ProblemsWhy should big data be more difficult to secure? In a word, variety. But the business won’t wait to use it to predict customer behavior, find correlations across disparate data sources, predict fraud or financial risk, and more.
