JethroData SQL On Hadoop
After two years of development, JethroData in October took the wraps off its SQL on Hadoop technology, what the company describes as the first analytic database that runs natively on Hadoop.
While Hadoop, with its Hadoop Distributed File System, is good for storing large volumes of data, it wasn't designed for data analysis tasks. JethroData's database software provides the indexing and columnar structure needed to run analytical queries against that data.
The software is currently in an early-release mode.
