--- 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.
