Hello,
We have to carry out some maintenance of our Druid
<https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Druid> public
cluster, which will unfortunately require a period of service downtime.
The work is scheduled for next Monday, March 16th at approximately 10:30
UTC and is expected to take between 30 and 60 minutes.
Systems adversely affected will be:
* Superset - when querying the Druid Public (AQS) database
* Analytics Query Services (AQS) APIs:
o
Edit Analytics
o
Editor Analytics
* Global Editor Metrics
o Mobile Apps activity tab
o Growth Team impact module
o Year in review
We will be upgrading the Druid cluster during this time, as well the
operating systems of the hosts that serve the cluster.
Sadly, we are unable to carry out a rolling upgrade of the Druid
cluster, so this downtime is unavoidable.
If you have any particular concerns or queries about this maintenance
window, then please get in touch and we can look into deferring or
rescheduling this work.
Kind regards,
Ben
