Previously, a pattern of periodic tasks was created where nodes, and in many cases, all nodes not actively locked nor those in maintenance state, were pulled in by a periodic task. These periodic tasks would then create tasks which generated additional database queries in order to populate the task object. With the task object populated, the driver would then evaluate if the driver in question was for the the driver interface in question and *then* evaluate if work had to be performed. However, that field containing a pointer to if work needed to be performed as often already queried from the database on the very initial query to generate the list of nodes to evaluate. In essence, we've moved this up in the sequence so we evaluate that field in question prior to creating the task, potentially across every conductor, depending on the query, and ultimately which drivers are enabled. This saves potentially saves hundreds of thousands of needless database queries on a medium size deployment per single day, depending on which drivers and driver interfaces are in use.

Team and repository tags
Overview
Ironic consists of an API and plug-ins for managing and provisioning physical machines in a security-aware and fault-tolerant manner. It can be used with nova as a hypervisor driver, or standalone service using bifrost. By default, it will use PXE and IPMI to interact with bare metal machines. Ironic also supports vendor-specific plug-ins which may implement additional functionality.
