Hello,
If you use wmfdata-python <https://github.com/wikimedia/wmfdata-python>,
please *upgrade it soon* to version 2.2.0 in order to allow its presto
support to keep working.
We have just deployed a new version of our conda-analytics
<https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Conda>
environment, which has this new version of wmfdata installed by default,
so you can use conda-analytics-clone to make a new, custom environment
for yourself. Alternatively, you can update it within your existing
environments with:
pip install --upgrade
git+https://github.com/wikimedia/wmfdata-python.git@release
This upgrade is necessary because we are in the process of improving our
Presto <https://wikitech.wikimedia.org/wiki/Analytics/Systems/Presto>
services, for which we need to change the TLS certificates that secure
our client connections to the Presto cluster. Versions of wmfdata-python
prior to v2.2.0 were hard-coded
<https://github.com/wikimedia/wmfdata-python/commit/b7b5df4651c880ad6fc0980c037e15feab879a88>
to use our Puppet based Certificate Authority.
We will implement a change
<https://gerrit.wikimedia.org/r/c/operations/puppet/+/709713> to the
Presto configuration to switch the certificates *around mid-January
2024*, at which point any versions of wmfdata-python prior to 2.2.0 will
cease to connect to Presto and will return an error. I will send further
updates nearer the time, with more precise dates.
Please do let me know if you have any queries or concerns about this change.
Kind regards,
Ben
