![]() ![]() In Ecotone Payload can be anything PHP class or array, XML, JSON, simple string.Įcotone follows principle that you should not be forced to use framework specific classes. Message is a class, which contains of Payload and Headers. Ecotone can be used with Symfony, Laravel or no extra framework at all.Įcotone has more similarities with Message Broker than with Task Queue. It provides implementation of Enterprise Integration Patterns and provides easy to work API that hides messaging details from application code. $bus->dispatch(new PlaceOrder('milk')) ĭispatch method takes class and based on class name looks for Message Handler that can handle that.Įcotone from the ground is built around messaging concepts. How Messages are send to the Message Handler? In Symfony Messenger Payload must be PHP Class.Īs long as you don’t want to extend basic functionality, you will not need to work with Symfony implementation of Message directly. Message (called Envelope) is a class, which contains of Payload (called Message) and Headers (called Stamps). Symfony Messenger has more similarities with Message Broker than with Task Queue. It provides a message bus with the ability to send messages and then handle them immediately in your application or send them through transports (e.g. Messenger introduces messaging solution in Symfony Framework. I will be following Messaging terms, however I will map those terms to implementation details of each of the frameworks. ![]() Let’s take a look on the abstraction that each of the Framework provides. This is abstraction, that hides complexity of constructing Messages and connecting to external platforms. To send messages to the channel, we are using Messaging Gateway. So how can Message Handler (Endpoint) stay unaware of Messaging and still receive and send Messages? It’s wrapped by Consumer, which depending on the need can be Event-Driven (executed synchronously) or Polling (asynchronous, polling the messages). This frees the application from integration concerns and to let it solves business problems. Most of the application’s code should be written without messaging in mind. In general, an application should not be aware that it is using Messaging. Endpoints are places where we process, transform or filter out the Messages, this is the place which we mostly call Message Handlers. Channels can be Point-to-point where only one consumer can receive message sent to the channel, or Publish-subscribe which broadcast the message to all subscribing endpoints. Messages are sent and received from Channels using Endpoints. Message Brokers can offload your workload, but also are great for building message flows and cross service communication, as by it nature they handle message distribution and decoupled communication. Thanks to that Publisher can be fully decoupled from the subscriber (consumer). ![]() In Publish and Subscribe, Message is published and any party that is interested can subscribe to it. ![]() Thanks to routing capabilities, Message Brokers can deliver the Message in Point To Point fashion or by Publish And Subscribe. The application makes actual meaning out of it. For Message Brokers, Message is just an information that is passed from one place to another. It allows for Message Routing based on different criteria or delivering copy of a message to multiple Consumers (Workers). On other hand Message Brokers like RabbitMQ provides more flexible way of working with messages. Task Queues are helpful with offloading the system workload They provide Point to Point Channels, which means we send Task (Message) and it will be delivered to exactly one Worker (Consumer). Task Queues provides full lifecycle support, so we can track status of given Task (ready to process, being processed, completed). Task or Job is describing what needs to be done and asynchronous Worker process handles it. Task Queues like Beanstalkd provides abstraction over Task (Message). There are different types of platforms that may be used to solve asynchronous processing in PHP, some of them are Task Queues and other are Message Brokers. Differences between Task Queues and Message Brokers Symfony Messenger, Laravel Queues and Ecotone Framework provides higher level abstraction for message processing that hides integration with given messaging platforms and introducing additional features. Messaging platforms (RabbitMQ, Kafka, SQS, etc) helps in solving those problems by increasing the amount of load system can take, introducing background processing and handling failure retries. It becomes standard to send an email after registration, call external Services or perform some intensive tasks. Putting all the logic inside simple Request - Response model becomes not enough for our current system needs. Message processing becoming more and more popular in PHP.
