### NEW COMPONENT! ###
Hello Apache DataSketches IPMC and Community,
1. This is a call for vote to release Apache DataSketches-java version:
1.0.0-incubating-RC2
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.
NOTE 2: This release contains some critical performance improvements
and bug fixes for Apache Druid.
NOTE 3: Changes from RC1: The previous RC1 had a bug in the release
script which caused the SHA512sum to fail. Some very minor updates to the
LICENSE, NOTICE, and pom.xml files. Otherwise no code changes.
A. Results from the PPMC vote:
- 3 (+1) votes. One of the votes was a Mentor.
- The vote thread can be found at the Permalink:
https://mail-archives.apache.org/mod_mbox/datasketches-dev/201909.mbox/%3CCA%2BUaPnsfS9YgXREXixxvGvKbF_aLbMTPN1hTjq1ewfa3k9JBJw%40mail.gmail.com%3E
B. Testing/actions/votes performed by the voters in the PPMC Stage 1:
- Alex Saydakov: (+1)
Verified signature and checksum.
The package looks fine. Licenses are present.
Unit tests run successfully.
- Jon Malkin: (+1)
Verified signature and checksum
Licenses/notices present, although I still need to learn details of
what
they're supposed to include so I just checked for non-empty files
Successfully compiled and ran unit tests.
- Furkan Kamaci: (+1)
- Incubating in name
- DISCLAIMER exists
- LICENSE and NOTICE are fine
- No unexpected binary files
- Checked PGP signatures
- Checked Checksums
- Code compiles and tests successfully run
Minor things:
1) You can update README file at GitHub both for how to compile it and
discussion & support. i.e.: https://github.com/apache/lucene-solr
2) Seems that project fails to run tests when folder name has space
character. (See Note below under Build and Test Guide)
C. Additional Notes:
- The LICENSE and NOTICE files may not be in their final form. All the
information is present, but some of the information in the NOTICE file
needs to be moved to the LICENSE file. This is the result of continued
discussions with Justin Mclean.

6. Build & Test Guide: (assuming you have Maven)
The DataSketches-java component is pure Java and is structured as a
Maven project. You must compile using JDK 8. There is one run-time
dependency of the DataSketches-memory component (recently released), and,
of course, a number of test and Maven plugin dependencies, all of which can
be resolved by Maven.
NOTE: The directory elements of the full absolute path of the target
directory for your unzipped archive must qualify as Java identifiers. In
other words,
the directory elements must not have any space characters (or non-Java
identifier characters) in any of the path elements.
This is actually required by the Oracle Java Specification in order to
ensure location-independent access to resources:
(
https://docs.oracle.com/javase/8/docs/technotes/guides/lang/resources.html).
This component does access resource files for testing. The next release
will have a fix that should be tolerant of spaces at least, but this note
should remain.
There are two types of tests: normal unit tests and tests run by the
strict profile. To run normal unit tests:
$ mvn clean test
To run the strict profile tests:
$ mvn clean test -P strict
To install jars in your local .m2 repository:
$ mvn clean install -DskipTests=true
7. Documentation: The documentation for the DataSketches Java component is
part of the website.
The Overview section on the website has extensive documentation on all
the sketches:
- https://datasketches.github.io
Javadocs:
- https://datasketches.github.io/api/core/snapshot/apidocs/index.html
8. This vote is the 2nd stage vote:
- This voting process will remain open for at least 72 hours
and until at least 3 (+1) IPMC votes or a majority of (+1) are
acquired.
Please vote accordingly:
[ ] +1 approve
[ ] +0 no opinion
[ ] -1 disapprove with the reason
Thanks,
