features:
- |
Adds support for deploying ``ovn-sb-db-relay``. By default, Kolla
automatically calculates the number of relay groups based on the size of
the ``ovn-controller`` group and the value of
``ovn_sb_db_relay_compute_per_relay`` (50 by default), rounding up. If you
do not want to use relays, set ``enable_ovn_sb_db_relay`` to ``no`` in
``globals.yml``.
upgrade:
- |
When upgrading, the new ``ovn-sb-db-relay`` containers are automatically
deployed unless you explicitly set ``enable_ovn_sb_db_relay`` to ``no``.
There are no special data migration or manual steps required to enable
``ovn-sb-db-relay``; it coexists alongside the existing OVN SB DB cluster.
