Parameter to Limit Maximum Allowed transaction Size, Like [wsrep_max_ws_size|https://mariadb.com/kb/en/galera-cluster-system-variables/#wsrep_max_ws_size], or like sql_select_limit, but for updates.

It is sometimes desirable to set a default maximum transaction size for sessions, raising the limit or lifting the restriction for specific privileged sessions when called for. Galera implements a similar system-wide limit with wsrep_max_ws_size. The idea here would be to have a similar parameter for standalone servers, ideally settable both globally and at the session level.
