It's a bit tricky because redis streams doesn't support the delay natively. I think we could probably implement something similar to Laravel where they basically put jobs with a delay into a sorted set sorted by the timestamp and when the consumer runs to pull a job, we first check the sorted set for jobs that are now available by the current timestamp, and if so, then we insert them into the queue.

Messenger: Sync & Queued Message Handling

Ping alexander-schranz! He and I had talked about this - I believe he also had a vision for how it should work, it just didn't get done in time. Could you share with us Alexander? I would implement it the following way to have both delayed message and still have the redis stream features available and I think ragboyjr did describe it the same way. In case of no delay we just push the message directly to the stream. But in case when it is a delayed message we push the message into a redis sorted set where the key of the sorted set is the timestamp when it should be executed.

In the get function we need first check the queue and push them then to stream if messages exist between 0 and current timestamp:. The only disadvantage is that the consumer need to handle the delayed queue so if your consumer is not a symfony application he need to implement the get logic with sorted set read and push to the stream itself aslong as redis does not support delayed messages itself.

Messenger component

I have a Symfony 4 application using the Symfony Messenger component version 4. For asynchronous message handling some Redis transports are configured and they work fine.

But then I decided that one of them should retry a few times when message handling fails. I tried replacing Redis with Doctrine as implementation of the retrying transport and voila - the delays started to work as expected. I therefore suspect that the Redis transport imlementation doesn't support delayed retry. But I read the docs carefully, searched related Github issues, and still didn't find a definite answer.

So my question is: does Redis transport support delayed retry? If it does, how do I make it work? It turned out that Redis transport supports delayed retry, but only since Messenger version 4.

Read this article for more details. The bus is used to dispatch messages. The behavior of the bus is in its ordered middleware stack. The component comes with a set of middleware that you can use. When using the message bus with Symfony's FrameworkBundle, the following middleware are configured for you:.

Every middleware needs to implement the MiddlewareInterface. Once dispatched to the bus, messages will be handled by a "message handler". A message handler is a PHP callable i.

The Messenger Component

If you need to add metadata or some configuration to a message, wrap it with the Envelope class and add stamps. For example, to set the serialization groups used when the message goes through the transport layer, use the SerializerStamp stamp:. Instead of dealing directly with the messages in the middleware you receive the envelope.

Hence you can inspect the envelope content and its stamps, or add any:. The above example will forward the message to the next middleware with an additional stamp if the message has just been received i. You can create your own stamps by implementing StampInterface. Alternatively, you can iterate through all stamps of a specific type by using the FQCN as first parameter of this method e.

Any stamp must be serializable using the Symfony Serializer component if going through transport using the Serializer base serializer. In order to send and receive messages, you will have to configure a transport.

A transport will be responsible for communicating with your message broker or 3rd parties. Imagine that you already have an ImportantAction message going through the message bus and being handled by a handler. Now, you also want to send this message as an email using the Mime and Mailer components.Messenger provides a message bus with the ability to send messages and then handle them immediately in your application or send them through transports e. To learn more deeply about it, read the Messenger component docs.

In applications using Symfony Flexrun this command to install messenger:.

Messenger centers around two different classes that you'll create: 1 a message class that holds data and 2 a handler s class that will be called when that message is dispatched. The handler class will read the message class and perform some task. Thanks to autoconfiguration and the SmsNotification type-hint, Symfony knows that this handler should be called when an SmsNotification message is dispatched.

Most of the time, this is all you need to do. But you can also manually configure message handlers.

To see all the configured handlers, run:. You're ready! By default, messages are handled as soon as they are dispatched. If you want to handle a message asynchronously, you can configure a transport. A transport is capable of sending messages e. Messenger supports multiple transports.

A transport is registered using a "DSN". Thanks to Messenger's Flex recipe, your. Uncomment whichever transport you want or set it in. See Transport Configuration for more details.

Now that you have a transport configured, instead of handling a message immediately, you can configure them to be sent to a transport:. Any messages not matched under routing will still be handled immediately. You can also route classes by their parent class or interface. Or send messages to multiple transport:.

If you need to pass a Doctrine entity in a message, it's better to pass the entity's primary key or whatever relevant information the handler actually needs, like emailetc instead of the object:.

If a message doesn't match any routing rulesit won't be sent to any transport and will be handled immediately. In some cases like when binding handlers to different transportsit's easier or more flexible to handle this explicitly: by creating a sync transport and "sending" messages there to be handled immediately:.

You can also create your own transport if you need to send or receive messages from something that is not supported.

Once your messages have been routed, in most cases, you'll need to "consume" them. You can do this with the messenger:consume command:. The first argument is the receiver's name or service id if you routed to a custom service. By default, the command will run forever: looking for new messages on your transport and handling them. This command is called your "worker".

Sometimes certain types of messages should have a higher priority and be handled before others. To make this possible, you can create multiple transports and route different messages to them. For example:. You can then run individual workers for each transport or instruct one worker to handle messages in a priority order:.

Supervisor is a great tool to guarantee that your worker process es is always running even if it closes due to failure, hitting a message limit or thanks to messenger:stop-workers.
