NAME MojoX::Plugin::AnyCache - Cache plugin with blocking and non-blocking support SYNOPSIS $app->plugin('MojoX::Plugin::AnyCache' => { backend => 'MojoX::Plugin::AnyCache::Backend::Redis', server => '127.0.0.1:6379', }); # For synchronous backends (blocking) $app->cache->set('key', 'value'); my $value = $app->cache->get('key'); # For asynchronous backends (non-blocking) $app->cache->set('key', 'value' => sub { # ... }); $app->cache->get('key' => sub { my $value = shift; # ... }); DESCRIPTION MojoX::Plugin::AnyCache provides an interface to both blocking and non-blocking caching backends, for example Redis or Memcached. It also has a built-in replicator backend (MojoX::Plugin::AnyCache::Backend::Replicator) which automatically replicates values across multiple backend cache nodes. SERIALISATION The cache backend module supports an optional serialiser module. $app->plugin('MojoX::Plugin::AnyCache' => { backend => 'MojoX::Plugin::AnyCache::Backend::Redis', server => '127.0.0.1:6379', serialiser => 'MojoX::Plugin::AnyCache::Serialiser::MessagePack' }); SERIALISER WARNING If you use a serialiser, "incr" or "decr" a value, then retrieve the value using "get", the value returned is deserialised. With the FakeSerialiser used in tests, this means 1 is translated to an "A". This 'bug' can be avoided by reading the value from the cache backend directly, bypassing the backend serialiser: $self->cache->set('foo', 1); $self->cache->backend->get('foo'); TTL / EXPIRES Redis Full TTL support is available with a Redis backend. Pass the TTL (in seconds) to the "set" method. $cache->set("key", "value", 10); $cache->set("key", "value", 10, sub { # ... }); And to get the TTL (seconds remaining until expiry) my $ttl = $cache->ttl("key"); $cache->ttl("key", sub { my ($ttl) = @_; # ... }); Memcached Full TTL set support is available with a Memcached backend. Pass the TTL (in seconds) to the "set" method. $cache->set("key", "value", 10); $cache->set("key", "value", 10, sub { # ... }); Unlike a Redis backend, 'get' TTL mode in Memcached is emulated, and the time remaining is calculated using timestamps, and stored in a separate prefixed key. To enable this, set "get_ttl_support" on the backend: $cache->backend->get_ttl_support(1); This must be done before setting a value. You can then get the TTL as normal: my $ttl = $cache->ttl("key"); $cache->ttl("key", sub { my ($ttl) = @_; # ... });
