We are glad to announce the release of: oslo.db 18.0.0 This release is part of the gazpacho release series. The source is available from: https://opendev.org/openstack/oslo.db Download the package from: https://pypi.org/project/oslo.db Please report issues through: https://bugs.launchpad.net/oslo.db/+bugs For more details, please see below. 18.0.0 ^^^^^^ New Features ************ * Add a new parameter named "synchronous_reader" for sqlalchemy backend so an operator can choose from configuration file if reader context should be synchronous or not. When "synchronous_reader" is set to "True" (the default), a database reader context will guarantee it can read data from a writer context by reusing the same "connection" parameter, thus ignoring the "slave_connection" parameter. When "synchronous_reader" is set to "False", a database reader context works the same as an async_reader and will select the "slave_connection" parameter to connect to the database if present. When setting this parameter to "False", make sure your cluster lag is not a problem or set "mysql_wsrep_sync_wait" accordingly. Upgrade Notes ************* * The "oslo_db.sqlalchemy.enginefacade.LegacyEngineFacade" class and related helpers, namely "_TransactionFactory.get_legacy_facade", "_TransactionContextManager.get_legacy_facade" and "get_legacy_facade" from the same module, have all been removed. The "LegacyEngineFacade" class has been deprecated since 1.12.0 in favour of using the "oslo_db.sqlalchemy.enginefacade" module directly. * Support for Python 3.9 has been removed. Now the minimum python version supported is 3.10.
