Mojo::Redis - Redis driver based on Mojo::IOLoop
use Mojo::Redis; my $redis = Mojo::Redis->new; $redis->db->set(foo => 42); $redis->db->expire(foo => 600); warn $redis->db->get('foo');
$redis->db->get_p("mykey")->then(sub { print "mykey=$_[0]\n"; })->catch(sub { warn "Could not fetch mykey: $_[0]"; })->wait;
Pipelining is built into the API by sending a lot of commands and then use "all" in Mojo::Promise to wait for all the responses.
Mojo::Promise->all( $db->set_p($key, 10), $db->incrby_p($key, 9), $db->incr_p($key), $db->get_p($key), $db->incr_p($key), $db->get_p($key), )->then(sub { @res = map {@$_} @_; })->wait;
Mojo::Redis is a Redis driver that use the Mojo::IOLoop, which makes it integrate easily with the Mojolicious framework.
It tries to mimic the same interface as Mojo::Pg, Mojo::mysql and Mojo::SQLite, but the methods for talking to the database vary.
This module is in no way compatible with the 1.xx version of Mojo::Redis and this version also tries to fix a lot of the confusing methods in Mojo::Redis2 related to pubsub.

This module is currently EXPERIMENTAL, and bad design decisions will be fixed without warning. Please report at https://github.com/jhthorsen/mojo-redis/issues if you find this module useful, annoying or if you simply find bugs. Feedback can also be sent to jhthorsen@cpan.org.

$cb = $redis->on(connection => sub { my ($redis, $connection) = @_; });
Emitted when Mojo::Redis::Connection connects to the Redis.
$str = $redis->encoding; $redis = $redis->encoding("UTF-8");
The value of this attribute will be passed on to "encoding" in Mojo::Redis::Connection when a new connection is created. This means that updating this attribute will not change any connection that is in use.
Default value is "UTF-8".
$int = $redis->max_connections; $redis = $redis->max_connections(5);
Maximum number of idle database handles to cache for future use, defaults to 5. (Default is subject to change)
$str = $redis->protocol_class; $redis = $redis->protocol_class("Protocol::Redis::XS");
Default to Protocol::Redis::XS if the optional module is available and at least version 0.06, or falls back to Protocol::Redis::Faster.
$pubsub = $redis->pubsub;
Lazy builds an instance of Mojo::Redis::PubSub for this object, instead of returning a new instance like "db" does.
$url = $redis->url; $redis = $redis->url(Mojo::URL->new("redis://localhost/3"));
Holds an instance of Mojo::URL that describes how to connect to the Redis server.
$db = $redis->db;
Returns an instance of Mojo::Redis::Database.
$cache = $redis->cache(%attrs);
Returns an instance of Mojo::Redis::Cache.
$cursor = $redis->cursor(@command);
Returns an instance of Mojo::Redis::Cursor with "command" in Mojo::Redis::Cursor set to the arguments passed. See "new" in Mojo::Redis::Cursor. for possible commands.
$redis = Mojo::Redis->new("redis://localhost:6379/1"); $redis = Mojo::Redis->new(Mojo::URL->new->host("/tmp/redis.sock")); $redis = Mojo::Redis->new(\%attrs); $redis = Mojo::Redis->new(%attrs);
Object constructor. Can coerce a string into a Mojo::URL and set "url" if present.
