This looks great! Very easy to read. One thing I noticed is that the comments in the code have better insight into how this is supposed to work than the documentation. Would be nice to get more details in the user-facing docs. Particularly the overlap with maintenance coordinators and this. Example questions I can imagine users having include: how would I run an update which adheres to the maintenance SLA but also never updates more than N total instances? They may be tempted to use the batch size for this and here it would drastically limit their throughput. - David McLaughlin On July 3, 2018, 11:29 p.m., Jordan Ly wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
