wsrep_sst_method=rsync
What method to use to copy database state to a newly joined node. Supported
methods:
- mysqldump: slow (except for small datasets) but allows for upgrade
between major MySQL versions or InnoDB features.
- rsync: much faster on large datasets (default).
- rsync_wan: same as rsync but with deltaxfer to minimize network traffic.
- xtrabackup: very fast and practically non-blocking SST method based on
Percona's xtrabackup tool.
