The application, having finished the critical read, disables wsrep_sync_wait, returning the node to normal operation. tbl_name and returns the number of For the multiple-table syntax, UPDATE updates rows in each table named in table_references that satisfy the conditions. column aliases are not used, or if they are the same as the If you wanted to replace the words with blank string, go with REGEXP_REPLACE(). tables listed before the FROM clause are I think there are similar implementations for MySQL, MSSql and Orable. This deprecates wsrep_causal_reads. The query gets more complex, you may have trouble isolating/excluding the FOUND_ROWS() result, and mysql_num_rows() will return the number of actual results + 1, all of which makes your code messier and harder to read. When you enable this parameter, the node triggers causality checks in response to certain types of queries. When the node loads the wsrep Provider, there are several configuration options available that affect how it handles certain events.
