Heat rather than running through them sequentially
This is a follow-up to the design summit discussion about DB migrations.
There was concern about the undo-ability of some migrations. The specific
example cited was removal of a column. Could that be done with the
following three migrations, each undo-able? First, change the code to
keep
It seems to me we have been discussing a proposal whose write-up
intertwines two ideas: (1) making software components look like resources,
and (2) using nested stacks and environments to achieve the pattern of
definitions and uses. The ideas are separable, and I think the discussion
has sort

This was actually discussed in the session as an example of how other
projects handle these problems. Our concerns (IIRC) were that it would

hard to land in

My 2c: the way I designed the Heat API was such that extant stacks can
be addressed uniquely by name. Humans are pretty good with names, not so
much with 128 bit numbers. The consequences of this for the design were:

There were some concerns expressed at the summit about scheduler
scalability in Nova, and a little recollection of Boris' proposal to keep
the needed state in memory. I also heard one guy say that he thinks Nova
does not really need a general SQL database, that a NOSQL database with a
bit of
