Now the client can discover the whole replication configuration by
asking to one of the servers (master has the precedence) using the
INFO REPLICATION command. This is obviously a best-effort fallback
and there is no strong guarantee about reliability and efficiency.
By enabling auto-discovery, the client automates this process when
the execution of a command fails because one of the target servers
is unreachable. The replication connection requires an instance of
connection factory associated to it in order to be able to create
new connections on the fly.
It is possible to enable the auto-discovery procedure easily via
client options:
$client = new Predis\Client($servers, [
'replication' => true,
'autodiscovery' => true,
]);
