Feature changes
BC break: Renamed plugin configuration setting
ini_file
toconfig_file
. In early versions the plugin configuration file used ini style. Back then the configuration setting was named accordingly. It has now been renamed to reflect the newer file format and to distinguish it from PHP's own ini file (configuration directives file).Introduced new default charset setting
server_charset
to allow proper escaping before a connection is opened. This is most useful when using lazy connections, which are a default.Introduced
wait_for_gtid_timeout
setting to throttle slave reads that need session consistency. If global transaction identifier are used and the service level is set to session consistency, the plugin tries to find up-to-date slaves. The slave status check is done by a SQL statement. If nothing else is set, the slave status is checked only one can the search for more up-to-date slaves continues immediately thereafter. Settingwait_for_gtid_timeout
instructs the plugin to poll a slaves status forwait_for_gtid_timeout
seconds if the first execution of the SQL statement has shown that the slave is not up-to-date yet. The poll will be done once per second. This way, the plugin will wait for slaves to catch up and throttle the client.New failover strategy
loop_before_master
. By default the plugin does no failover. It is possible to enable automatic failover if a connection attempt fails. Upto version 1.3 onlymaster
strategy existed to failover to a master if a slave connection fails.loop_before_master
is similar but tries all other slaves before attempting to connect to the master if a slave connection fails.The number of attempts can be limited using the
max_retries
option. Failed hosts can be remembered and skipped in load balancing for the rest of the web request.max_retries
andremember_failed
are considered experimental although decent stability is given. Syntax and semantics may change in the future without prior notice.
