• v1.0.GA Changes

  July 09, 2013

  📚 Current Bolt release is 1.0 GA which is released on 9th of July, 2013. BOLT was made Open Source on Github with Apache License with 1.0 Beta. This is the second release post the 1.0 Beta drop. For Bolt related documentation go to the BOLT wiki page. To download the BOLT Binaries go to Bolt Landing Page

  🚀 This release contains the following features:

  • Serial code paths for all routines including routines which do not have a TBB implementation.
  • 🐎 Performance optimizations for Scan and scan by key, Sort and Stable Sort routines. (Up to 45% for Scan routines for certain data sizes)
