Currently, all compute nodes update status info in the DB on a periodic basis (the period is currently 60 seconds). Given that the status of the node only changes at specific points (manyline image creation/destruction) this leads to significant DB overhead on a large system. This BP changes the update mechanism to only update the DB when a node state changes, specifically at node startup, instance creation and instance destruction.

OpenStack Nova Specifications
This git repository is used to hold approved design specifications for additions to the Nova project. Reviews of the specs are done in gerrit, using a similar workflow to how we review and merge changes to the code itself.
The layout of this repository is:
specs/<release>/You can find an example spec in doc/source/specs/template.rst.
Specifications are proposed for a given release by adding them to the specs/<release> directory and posting it for review. The implementation status of a blueprint for a given release can be found by looking at the blueprint in launchpad. Not all approved blueprints will get fully implemented.
Specifications have to be re-proposed for every release. The review may be quick, but even if something was previously approved, it should be re-reviewed to make sure it still makes sense as written.
Prior to the Juno development cycle, this repository was not used for spec reviews. Reviews prior to Juno were completed entirely through Launchpad blueprints:
