Jethro - We Make Real-Time Business Intelligence Work on Hadoop


Jethro 1.6.0 Released

By Jethro on April 21, 2016


The main themes of Jethro 1.6.0 are concurrency and new range-index features.

Concurrency features are:

  • Reuse of results when the same “where” clause is used by multiple queries, in order to reduce resource consumption and increase concurrency.

  • Enhanced locking infrastructure to protect against deadlocks during high load.

  • Increase the maximum number of threads allocated by the operating system to be used by the Jethro services

Range Indexes:

This new feature allows you to create special indexes for ranges of values.  This significantly increases the performance of queries that employ wide range of column values in filters.
