[VOTE] MADlib v1.19.0-rc2

[Orhan Kislal <ok...@vmware.com>]

Hello, Apache MADlib community,

This is the vote for Apache MADlib 1.19.0 Release (RC2). It provides the source release tarball and convenience binaries.

The vote will run for at least 72 hours and will close on Feb 18th, 2022 @21:00 UTC (16:00 EST). A minimum of 3 binding +1 votes and more binding +1 than binding -1 are required to pass.

The main goals of this release are:

New features:
    - DBSCAN: Fast parallel-optimized DBSCAN (MADLIB-1017, MADLIB-867)
    - MLP: Add rmsprop and Adam optimization techniques (MADLIB-1434, MADLIB-1435)

Improvements:
    - Graph: Improve WCC subtx count and catalog entry frequency
    - MLP: Set lambda value for minibatch

Bug fixes:
    - PMML: Rename builder.py to circumvent ignore scripts
    - DL: Fix object table schema error message
    - DL: Fix metrics error message
    - DL: Remove AOcontrol from load_top_k_accuracy fn

Other:
    - DEBUG: Add WithTracebackForwarding() macro and report_segment_tracebacks param
    - Jenkins: Add new dockerfile for PG11 (MADLIB-1469)
    - Build: Use dynamic_library_path for module pathname

NOTE:
This release changes MADlib library location and updates UDF definitions. Views depending directly on madlib defined function(s) have to be dropped before upgrading. pg_ctl has to be in the environment PATH for the installation process to correctly set the dynamic_library_path value.

Ubuntu 18.04 GPDB 6.*, PostgreSQL 11 (compiled with gcc 7.4.0)
Please note that the official Ubuntu repositories do not contain binaries for PostgreSQL 12 with Python 2 support (MADlib does not work with Python 3 at this point). While it is possible to configure and compile PostgreSQL 12 manually and compile MADlib 1.19.0.RC2 from source to work with it, this binary does not have the support for such a use case.

macOS: 11.6 GPDB 5.* & 6.*, PostgreSQL 11 & 12 (compiled with Apple clang 12.0.0)
Please note that, unlike previous MADlib releases, 1.19.0 does not have a dmg file for macOS systems because the PackageMaker tool is not usable with modern systems. Instead, we prepared a tarball containing the MADlib installation folder. Please refer to the Readme_OSX file included in the tarball for instructions.
