NAME
Redis::Transaction - utilities for handling transactions of Redis
SYNOPSIS
use Redis;
use Redis::Transaction qw/multi_exec watch_multi_exec/;
# atomically increment foo and bar. It will execute following commands typically.
# > MULTI
# > INCR foo
# > INCR bar
# > EXEC
multi_exec Redis->new, 10, sub {
my $redis = shift;
$redis->incr('foo');
$redis->incr('bar');
};
# atomically increment the value of a key by 1 (let's suppose Redis doesn't have INCR).
# It will execute following commands typically.
# > WATCH mykey
# > GET mykey
# > MULTI
# > SET mykey, 1
# > EXEC
watch_multi_exec Redis->new, ['mykey'], 10, sub {
my $redis = shift;
return $redis->get('mykey');
}, sub {
my ($redis, $value) = @_;
$redis->set('mykey', $value + 1);
};
