Jethro is an acceleration server for the Business Intelligence (BI) on big data use case. With Jethro, big data visual analytics on BI tools like Tableau, Qlik or MicroStrategy, perform at interactive-speed while directly connected to a big data source. The server enables near-real-time access with incremental updates. Jethro is a combination of two engines: columnar SQL database and search indexing. Think Impala plus Elastic Search, in one product. It looks and behaves like a SQL engine but leverages the full-indexing engine inside to power fast queries. Indexing, smart caching and micro auto-cubes work in tandem to deliver the fastest interactive BI experience. Jethro is needed when extracts are too big or slow and data needs to be accessed at the source. The server is compatible with Hadoop and any data source and big data platform. It is optimal for 0.5B - 10B row datasets. Jethro supports complex data models like star and snowflake schema. It enables set analysis functionality such as "include/exclude filters" and "total function"
