1. This is a call for vote to release Apache DataSketches-java candidate
version: 4.0.0-RC3
NOTE: This is the core Java component of the DataSketches library that
includes all the sketch algorithms in production-ready packages. These
sketches can be called directly from this component or used in conjunction
with the adaptor components such as Hadoop Pig, Hadoop Hive, or the
aggregator adaptors built into Apache Druid.
MAJOR NEW FEATURES AND ENHANCEMENTS FOR USERS
- Quantile Sketches
- The major APIs for all the quantile sketches now derive from
interfaces common to all the quantile sketches. This makes it much easier
for the user to move from one quantile sketch to another with only very
minor code changes.
- All the quantile sketches now have a "SortedView", which is
iterable and makes analysis of the quantile distribution even easier.
- HLL Sketches
- Major speed performance improvements for HLL union/merge
operations.
- Major improvements to the HLL Javadocs.
- Theta Sketches
- The Theta sketch has been enhanced with an optional compress
operation that makes the serialized theta sketch smaller.
- TestNG has been updated to version 7.5.1 (works with Java 8), which
includes the Zip Slip Vulnerability fix.
CORRECTIONS FROM -RC2
- The maven version was inadvertently set at 3.9.1, which was
unnecessarily high. It was changed back to 3.5.0.
