<div dir="ltr">The restore use case is for sure inconsistently implemented and used. I think I agree with Boris that we treat it as separate and just move on with cleaning up soft delete. I imagine most deployments don't like having most of the rows in their table be useless and make db access slow? That being said, I am a little sad my hacky restore method will need to be reworked :-).<div>

</div>That seems like an unreasonable request of low level tools like Nova. End<br>
user applications and infrastructure management should be responsible<br>
for these things and will do a much better job of it, as you can work<br>
your own business needs for reliability and recovery speed into an<br>
application aware solution. If Nova does it, your cloud just has to<br>
provide everybody with the same un-delete, which is probably overkill<br>
for _many_ applications.<br>
