Use to request the service level eventual consistency from the
mysqlnd_ms_set_qos. Eventual consistency is the default
quality of service when reading from an asynchronous MySQL
replication slave. Data returned in this service level may or may not
be stale, depending on whether the selected slaves happen to have
replicated the latest changes from the MySQL replication master or
not.
Use to request the service level session consistency from the
mysqlnd_ms_set_qos. Session consistency is defined as read
your writes. The client is guaranteed to see his latest changes.
Use to request the service level strong consistency from the
mysqlnd_ms_set_qos. Strong consistency is used to ensure all
clients see each others changes.
Used as a service level option with
