Hello,
We are going to be carrying out a short maintenance operation on our Presto cluster on Monday morning at approximately 11:00 UTC. There may be a few minutes where Presto is unavailable and this may have an impact on Superset dashboards that use Presto. We hope to keep this period of instability to the region of 5-10 minutes.
Specifically, the work involves moving the presto co-ordinator role as part of a server refresh. (T336045 https://phabricator.wikimedia.org/T336045)
We have attempted to make sure that this is a non-breaking change, especially for any users of wmfdata-python https://github.com/wikimedia/wmfdata-python.
If this maintenance window is inconvenient for you, please do let us know and we can look to defer the work. Similarly, if you notice anything unusual afterwards, please let us know.
Kind regards, Ben
