Ecosystem Integrations

  • Optimized Swift connector:
    • Alluxio Swift connector read performance improved by 2x
    • Enabled large directory listings with pagination
    • Improved sync and persist logic
  • Improved S3A connector:
    • Alluxio S3A connector write performance improved by 2x
    • Support for user defined S3 storage endpoint
  • More flexible Mesos integration:
    • Ability to specify which machine the Alluxio master will be deployed on
    • Support for launching user defined Alluxio distributions
  • Support for HBase:
    • Integration for running HBase on top of Alluxio, see the documentation for more details

    • Integration for running MapR-FS as an under storage for Alluxio, see the documentation for more details

Usability Improvements

  • Improved metrics collection:
    • Alluxio metrics collection is easily integrated with 3rd party metrics systems
    • More accurate metrics by separating client and server metrics
  • Full support for the Alluxio user concept and permission control:
  • More lightweight Alluxio client dependencies:
    • Under storage delegation is enabled by default, meaning only servers need under storage connector libraries. See the configuration documentation for the different settings available.
    • Prevents client side dependency and configuration conflicts

Performance Improvements

  • Optimized small random read performance (ie. for SQL workloads):
    • Read latency improved by up to 10x
    • Read IOPS improved by up to 2x
  • Improved Alluxio interprocess communication performance and scalability:
    • Removed client side limit on number of concurrent operations
    • Decreased overhead of client operations through persistent connections
