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.

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.
