[ANNOUNCE] YCSB 0.4.0 Release
On behalf of the development community, I am pleased to announce the
release of YCSB 0.4.0.
Highlights:
* Default measurement changed from histogram to hdrhistogram.
* Users who want previous behavior can set the 'measurementtype'
property to 'histogram'.
* Reported 95th and 99th percentile latencies now in microseconds
(previously in milliseconds).
* The HBase Binding has been split into 3 seperate bindings based on
your version of HBase and
the names have changed to hbase10, hbase098, and hbase094.
Bug Fixes:
* Previously, with hdrhistogram, the 95th percentile actually reported
the 90th percentile value. It now reports the actual 95th percentile value.
* Fixed a race condition between insert and read/update operations.
Full release notes, including links to source and convenience binaries:
https://github.com/brianfrankcooper/YCSB/releases/tag/0.4.0
This release covers changes from the last 2 months.
