JethroData is an innovative index-based SQL engine for Hadoop , focusing on interactive queries for business users. It leverages its indexes to deliver great query performance, while requiring minimal Hadoop cluster resources. JethroData is a great fit for interactive BI and real-time dashboards on Hadoop. JethroData's indexes are sorted, multi-hierarchy, compressed bitmaps. They are created automatically for every column, and are written in an efficient, append-only fashion – avoiding expensive random writes and locking. Queries use indexes to read only the data they need, instead of performing full scans, leading to faster response times. The key to JethroData’s superior performance is its unique indexing technology. JethroData’s nodes are stateless and highly elastic, allowing easy scale-out to meet concurrency requirements.
