-Subject: [PATCH] Allow configuring MySQL WSREP SST provider
-
-On some arm64 platforms xtrabackup is broken due to an outdated
-MySQL/InnoDB code that it uses which is missing. To work around that
-this patch allows choosing which WSREP SST provider to use. Aside of
-already supported `xtrabackup-v2` and `mysqldump`, the `rsync` method
-has been added as it is comparable to xtrabackup in terms of speed (or
-is faster), has been validated to work on arm64 platforms where
-xtrabackup is broken and it doesn't rely on db mechanisms to perform the
-state transfer.
-
-This patch is tied to a patch in fuel-web that introduces configuration
-options for WSREP SST provider and in case nothing is specified, it
-will choose `xtrabackup-v2`.
