A whiel ago, when one neede to execute DML changes (insert/update/delete) on a node without submitting them to the galera replication by setting sql_log_bon=off.

while the fix is good, sometimes we can still have the need to modify datas in a single node of a cluster to avoid triggering massive SSTs and this is not doable anymore.

can we introduce a session only dynamic variable that disable galera replication on commit :

sqlprompt > set session wsrep_local_commit = yes;
sqlprompt > bunch of DMLs
sqlprompt > commit;
sqlprompt > set session wsrep_local_commit = no;

USE CASE :
massive dataset (in the To range)
one small table is messed up during an RSU delivery (a few 100s Mbs)

triggering an SST i that case would be a waste of time and ressources while a simple set of DML instructions would solve the issue.
