This is useful to avoid guessing the correct server instance at runtime
thus reducing the overhead of a guess-and-try approach since relying on
-ASK or -MOVED responses returned by a node is a costly operation.
For now, you can pre-associate slots using the "cluster" client option:
$parameters = array(
'tcp://127.0.0.1:6379',
'tcp://127.0.0.1:6380',
'tcp://127.0.0.1:6381',
);
$options = array(
'cluster' => function ($options) {
$cluster = new Predis\Connection\RedisCluster();
$cluster->setSlots(0, 1364, '127.0.0.1:6379');
$cluster->setSlots(1365, 2729, '127.0.0.1:6380');
$cluster->setSlots(2730, 4095, '127.0.0.1:6381');
return $cluster;
},
);
$client = new Predis\Client($parameters, $options);
In the future we will make the slots configuration easier by fetching
the configuration from a node using the command "CLUSTER NODES" or by
pre-computing the slices of slots associated to a node when adding it
to the cluster connection object.
