Bug Description

Newer features like parallel, compress etc. are only available in xbstream. Hence wsrep_sst_xtrabackup needs to be modified to support that.

Is it possible to enable/disable these features via the my.cnf ([xtrabackup] section?) without modifying the script? Can we get a doc bug on that if so?

Also, I believe if we compress with xbstream, we need some scripting to unpack the files on the JOINER side, is that implemented too?

Yes, it is possible. For details you can look at https://bazaar.launchpad.net/~raghavendra-prabhu/percona-xtradb-cluster/release-5.5.31/revision/389

Yes, there is also a doc bug - https://bugs.launchpad.net/bugs/1179447 (meant for next milestone but I can add it to this one if required).

b) Also, I believe if we compress with xbstream, we need some scripting to unpack the files on the JOINER side, is that implemented too?

Yes, xbstream is the streaming format and commit in this bug adds
'xbstream -x -C ...' part.

For decompression, you can again look at already committed https://bazaar.launchpad.net/~raghavendra-prabhu/percona-xtradb-cluster/release-5.5.31/revision/389

That has the details.
