For the anti-affinity use case, it's really useful for smaller or medium
size operators who want to provide some form of failure domains to users
but do not have the resources to create AZ's at DC or even at rack or
row scale. Don't forget that as soon as you introduce AZs, you need to
grow those AZs at the same rate and have the same flavor offerings
across those AZs.
For the retry thing, I think enough people have chimed in to echo the
general sentiment.
The purpose of my ML post was around getting rid of retries, not the
usefulness of affinity groups. That seems to have been missed, however.
Do you or David have any data on how often you've actually seen retries
due to the last-minute affinity constraint violation in real world
production?
