Thank you Sjoerd,

When you say python integration will be available in the Dec2016 release, that means I dont have to compile from source to have this feature, I can directly use one of the distribution you provide? Does the same thing apply for RIntegration, is it going to be supported in Dec2016 without any source compilation? Where I can check the upcoming release dates, with the features packaged?

It depends on which distribution you want to use. It's available for Fedora, CentOS 7, Debian 8, and Ubuntu (not precise). Not for any of the other binary distributions that we make. And when I say it's available, you do need to install a separate package (Fedora: MonetDB-python2 and MonetDB-R, Debian and Ubuntu: monetdb-python2 and monetdb-r). Releases are always a surprise (as in, we also don't know when exactly). The intention is still to release this year. For a sneak preview, try yum --enablerepo=monetdb-testing upgrade MonetDB\* I can already say this is not going to be the final release, but the difference with the final release should be small.

As for the flag to use when compiling from source, I am currently using the following:

./configure --enable-rintegration=yes --prefix=/home/centos/monetdb --enable-testing=no --enable-developer=no --enable-debug=no --enable-optimize=yes --enable-int128=yes

Anything to add if I need to run in a prod environment?

To get Python integration, you may want to add --enable-pyintegration=yes. Also make sure all required packages are installed. For Inspiration see the MonetDB.spec file (I assume you're doing this on CentOS from the command line).

Thank you.

Currently the release version is june2016, candidate is dec 2016, dev is the default. Is the python integration only supported on default branch? Any plan to move it to stable branch?

Python integration is available in the upcoming Dec2016 release (i.e. the candidate branch).
