Hello,

If you use 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 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 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 to use our Puppet based Certificate Authority.

We will implement a change 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
