Databases clusters can deliver different levels of consistency. As of PECL/mysqlnd_ms 1.2.0 it is possible to advice the plugin to consider only cluster nodes that can deliver the consistency level requested. For example, if using asynchronous MySQL Replication with its cluster-wide eventual consistency, it is possible to request session consistency (read your writes) at any time using mysqlnd_ms_set_quos(). Please, see also the service level and consistency introduction.

Example #1 Recap: quality of service to request read your writes

/* Request session consistency: read your writes */
if (!mysqlnd_ms_set_qos($mysqli, MYSQLND_MS_QOS_CONSISTENCY_SESSION))
  die(sprintf("[%d] %s\n", $mysqli->errno, $mysqli->error));
