"""Defines interface for DB access.
|
|
|
|
The underlying driver is loaded as a :class:`LazyPluggable`.
|
|
|
|
Functions in this module are imported into the cinder.db namespace. Call these
|
|
functions from cinder.db namespace, not the cinder.db.api namespace.
|
|
|
|
All functions in this module return objects that implement a dictionary-like
|
|
interface. Currently, many of these objects are sqlalchemy objects that
|
|
implement a dictionary interface. However, a future goal is to have all of
|
|
these objects be simple dictionaries.
|
|
|
|
|
|
**Related Flags**
|
|
|
|
:backend: string to lookup in the list of LazyPluggable backends.
|
|
`sqlalchemy` is the only supported backend right now.
|
|
|
|
:connection: string specifying the sqlalchemy connection to use, like:
|
|
`sqlite:///var/lib/cinder/cinder.sqlite`.
|

:enable_new_services: when adding a new service to the database, is it in the

pool of available hardware (Default: True)
