lgtm. Per the mariadb manual, wait 2 will wait to acquire locks for two seconds: https://mariadb.com/kb/en/wait-and-nowait/

Based on my reading of our metrics, this is an acceptable value. Longer waits are quite rare.

Do we need to add any extra error handling to partman to handle the new timeout errors we'll get?

We probably should, the MySQL command will return error, which is already accounted for, but the metrics wouldn't get updated. I've got an improvement, thanks @mcpherrinm!


all_results = dict()
for table in conf.tables:
time_start = None

I was confused when reviewing but I see we set time_start to now on line 345; this is just to pull it into a higher scope
