[sjaakola]

Document the accepted values for wsrep_sst_method variable.
Validity checks for this variable will be worked on by: https://github.com/codership/mysql-wsrep-bugs/issues/1594

So, I have found docs in:

• percona - https://docs.percona.com/percona-xtradb-cluster/8.0/wsrep-system-index.html#wsrep_sst_method
• a website - https://virtual-dba.com/blog/mariadb-galera-cluster-explained/
• mariadb - https://mariadb.com/kb/en/galera-cluster-system-variables/#wsrep_sst_method

and on galera cluster very own website:
https://galeracluster.com/library/documentation/mysql-wsrep-options.html#wsrep-sst-method

@sjaakola can you tell me what else needs to be done, so I can assign it appropriately?

@byte I guess the following changes are needed:

• xtrabackup becomes xtrabackup-v2
• Add ist-only
• Remove rsync_wan
• Add mariabackup

@byte I guess the following changes are needed:

• xtrabackup becomes xtrabackup-v2
• Add ist-only
• Remove rsync_wan
• Add mariabackup

We actually include:
wsrep_recover
wsrep_sst_clone
wsrep_sst_common
wsrep_sst_mysqldump
wsrep_sst_rsync
wsrep_sst_xtrabackup
wsrep_sst_xtrabackup-v2

also @sjaakola did we ever port this? I can't find the test, so i'm guessing validiting checking isn't ready yet

Worth noting the above is for Galera Cluster with MySQL 8

From MariaDB Server 10.11:
wsrep_sst_common
wsrep_sst_mariabackup
wsrep_sst_mysqldump
wsrep_sst_rsync
wsrep_sst_rsync_wan

and wsrep_sst_rsync_wan is a symlink to wsrep_sst_rsync
