Good morning,
I have to perform some scheduled maintenance on one of the analytics MariaDB replicas next week under ticket T343109.
Specifically, this is the replica we have of the s2 shard, which is accessible through the s2-analytics-replica.eqiad.wmnet alias. I have to rebuild this shard from a backup as a preventative measure.
I expect this shard to be unavailable for a few hours next Tuesday October 24th, starting from approximately 09:30 UTC, whilst the rebuild is taking place. This downtime may affect you if you:
- Use the analytics-mysql wrapper from stats servers
- Use the wmfdata-python or wikimedia-discovery-wmf libraries to read from the analytics replicas
Please let me know if this maintenance window will adversely affect your work and I will try to reschedule it.
If you have any questions or comments, please don't hesitate to get in touch.
Kind regards,
Ben
