Hello,

A new question has been asked in "MariaDB Galera Cluster" by gijs. Please answer it at http://mariadb.com/kb/en/sst-smethod-rsync_wan/ as the person asking the question may not be subscribed to the mailing list.

--------------------------------
I'm looking for an option to make my SST faster. I tried using xtrabackup-v2 but this currently doesn't support GTID clusters.

I read that there is a rsync SST method that is customized for WAN usage. It makes use of delta transfers to reduce the data that has to be send over the WAN.

I've tried:
wsrep_sst_method=rsync-wan
wsrep_sst_method=rsync_wan

But neither of them work, nor can I find any official documentation about this feature for MariaDB.

I did find: 
http://galeracluster.com/documentation-webpages/statetransfer.html
http://galeracluster.com/documentation-webpages/sst.html
http://galeracluster.com/documentation-webpages/mysqlwsrepoptions.html#wsrep-sst-method
https://blog.adminfactory.net/mariadb-and-galera-on-aws-amazon-linux.html

My question is how can I enable the delta transfer for rsync with MariaDB 10.1.12?

If this is not possible with MariaDB I'd like to know if there are any plans to implement it and if there are any plans to make xtrabackup-v2 support GTID clusters.
