[Buildbot-devel] Feedback on message queuing design

[Dustin J. Mitchell]

I've written up some documentation for a message-queuing design
covering the data that's already in the database:
  http://knuth.r.igoro.us/~dustin/buildbot-docs-mq/developer/mq.html
  https://raw.github.com/djmitche/buildbot/mq/master/docs/developer/mq.rst

I'd like to get some feedback - particularly from Amber and Tom, if
you have time, but of course the more the merrier.

There's more that will be included in 0.9.0, but I haven't fleshed it
out yet.  Briefly: Build status will migrate to the database.  Most
build information will be stored in a simple, flat form, but logs will
be stored as "chunks" in a searchable format.  The JSON interface will
be expanded to serve all data available in the database, with minimal
translation of the current database API.  The JSON interface will also
sport a means of consuming messages.  All of the code that's currently
based on someobject.subscribeToSomeEvent will be converted to an mq
consumer.  All of the code that currently implements IStatusReceiver
will be converted to an mq consumer.

Let me know what you think!
