Jethro Data is a BI acceleration and SQL-on-Hadoop query engine designed to make interactive analytics feasible on very large datasets stored in Hadoop-compatible storage. The vendor describes Jethro as a middle tier between BI tools (e.g., Tableau, Qlik, MicroStrategy) and the underlying data platform, using full indexing, caching, and automated aggregations to reduce query latency and increase concurrency compared with scan-based query engines.
On product pages, the vendor claims fast response times on very large datasets and support for high concurrency, while reducing the need for manual tuning and manual data engineering. These are vendor claims and should be validated in a proof-of-concept under representative workloads.
