Hello Apache DataSketches Community, 1. This is a call for vote to release Apache DataSketches-memory version: 1.0.0-incubating-RC1
NOTE 1: This is one component of the DataSketches library which needs to be released first as other repositories have a dependency on this one. Once this is released, the other components of the library will be able to be released. NOTE 2: All of the code has been properly refactored with "org.apache.datasketches...". All source files have the proper Apache license and have been checked with the Maven Rat Plugin. The code passes all tests with a coverage of > 98%. 2. The release candidate: https://dist.apache.org/repos/dist/dev/incubator/datasketches/memory/1.0.0-incubating-RC2/apache-datasketches-memory-1.0.0-incubating-src.zip 3. Source repository: https://github.com/apache/incubator-datasketches-memory Git Tag for this release: https://github.com/apache/incubator-datasketches-memory/tree/1.0.0-incubating-RC2 Git HashId for this release starts with: ec8f16e The artifacts have been signed with --keyid-format SHORT : 8CD4A902 4. Repository: dist.apache.org repository: The public signing key can be found in the KEYS file: https://dist.apache.org/repos/dist/dev/incubator/datasketches/KEYS Upon acceptance, the above artifacts will be deployed into the official Apache release repository: https://dist.apache.org/repos/dist/release/incubator/datasketches/memory/ 5. Repository: Maven Central (repository.apache.org): Upon acceptance the jar artifacts will be generated from the source repository and deployed to the Apache Maven Central staging repository: https://repository.apache.org/content/groups/staging/org/apache/datasketches/memory/ And then released into https://repository.apache.org/content/repositories/releases/datasketches/memory/ 6. Build Guide: The DataSketches-memory component is pure Java and is structured as a Maven project. You must compile using JDK 8. There is one run-time dependency and, of course, a number of test and Maven plugin dependencies, all of which can be resolved by Maven. This component is a set of low-level library functions that is used by the other DataSketches components. It has no user interface so the only thing you can do is compile and run the unit tests. 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 Note also that when running the test suite, you might get the following message: SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. This is normal. It just indicates that in your environment, you do not have a logger in your class-path so the default logger of a no-op is used instead. To install jars in your local .m2 repository: $ mvn clean install 7. If you are interested in the actual functions of the Memory, you will need to write some code that calls the Memory functions. The documentation for the DataSketches Memory component is part of the website. Overview documentation: - https://datasketches.github.io/docs/Memory/MemoryPackage.html - https://datasketches.github.io/docs/Memory/MemoryPerformance.html Javadocs: https://datasketches.github.io/api/memory/snapshot/apidocs/index.html This particular component has been split out from the rest of the DataSketches code because there have been a number of requests from folks that are interested in these high-performance functions independently of the remainder of the DataSketches library. 8. The vote will be performed in two stages: - This letter will be published on dev@ open for at least 72 hours or until necessary number of votes are reached. - This letter will be published on incubator@general for at least 72 hours or until necessary number of votes are reached. Anybody can vote, but only IPMC member's votes count. Please vote accordingly: [ ] +1 approve [ ] +0 no opinion [ ] -1 disapprove with the reason Thanks, The Apache DataSketches Team
