### Introduction of new Generic KllItemsSketch, Now, the nearly optimal and
high performing KLL quantile sketching algorithm can be used with
arbitrary types.
### We have a new capability for testing our sketches across languages.
For example, generating sketches in C++ and testing them in Java, and
visa-versa.
This will substantially improve user confidence that systems where
sketches need
to move across C++, Python and Java will work as intended.
(Python sketches are wrappers around the C++ implementations)
Hello Apache DataSketches PMC and Community,
1. This is a call for vote to release Apache DataSketches-java candidate
version: 4.2.0-RC1
NOTE 1: 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.
