It it has the ability to cache directly as well, but it has been effective (so far) for our use-case. That being said, I am unsure if caching in front of MySQL is really what we want. I believe that we should be caching after processing work (hence memoization mechanism) instead of at the SQL layer. This also means we can be measured in what we cache (oh hey, it makes no sense to cache X because it needs to be real time or there isn't a performance issue with that query / call, but Y does a ton of processing and is an expensive join/temptable query). In my experience, unless the whole application is designed with caching in mind, caching something as broad as MySQL calls (or any SQL store) is likely going to net exactly what Shawn Hartsock stated, adding a second performance issue. --Morgan On Mon, Oct 28, 2013 at 10:05 AM, Shawn Hartsock hartso...@vmware.commailto:hartso...@vmware.com wrote: I once heard a quote..

Re: [openstack-dev] [Ceilometer] Suggestions for alarm improvements ...
Sandy, Does the framework account for customizable events?: In my use case, I have a network (or some other proprietary way, e.g., some special BUS protocol) attached device that does not fit into openstack node structure. It can generate events. According to these events, Openstack orchestration layer (HEAT?) may need to do thing like failing over all vms on one system to another system (compute node). If I would like to use the alarm/notification system, I would need to add a Customized collector, and my events would need to be routed to, say HEAT, and I would need to define the action ( a plugging/callback?) corresponding to the event for HEAT to take on my behalf. Is my approach right/supported under the framework and the current HEAT (or some other components) release?

If a company is colluding with other core members, from the same company, to do bad things within a project, it should become pretty obvious at some point and the project's community should take action. If someone is putting in an extra effort to provide quality code and reviews on a regular basis, then why wouldn't we want that person on the team? Besides, being a core member really just means that you are required to do reviews and help out with the community. You do get some gerrit privileges for reviews, but that's about it. I for one think that we absolutely can use more core members to help out with reviews during the milestone deadlines :) Walt, As I said, I really wasn't worried about anyone colluding or doing bad things.

Re: [openstack-dev] Should RPC consume_in_thread() be more fault tolerant?
In this case, the exception is just hard to debug, and not something we expected in our design. The thorough solution would be to debug further to see the root cause, and deal with it as I suggested in the code review. However, If it is time consuming to debug, we can put the patch in there with logging to record the circumstances the 'unexpected' exception occurs, so that we can put in new patches to deal it when it becomes expected. After all, this is an iterative process. When the software evolves, a lot of unexpected has become expected. -Original Message- From: Raymond Pekowski (Code Review) [mailto:rev...@openstack.org] Sent: Tuesday, June 25, 2013 9:52 AM Cc: Dirk Mueller; Andrea Rosa; Ben Nemec; Chris Behrens; Eric Windisch; Russell Bryant; Qing He Subject: Change in openstack/oslo-incubator[master]: Make AMQP based RPC consumer threads more robust Raymond Pekowski has posted comments on this change.

Clarify, operator does not have to go through a long log to find the issue. Instead, he/she needs to be notified that something severe/unexpected just happened and he/she needs to check it out.
