Top 8 Things to know about Memphis {dev} | The Best Message Broker

Memphis{dev} is a software in which the topics are defined – consider the topics as a category – here, applications can add, process, and reprocess records. Micro-services or applications connect to message brokers to transfer a record onto the topic. Records can include any type of information about an event that has taken place on a website or any event that is supposed to trigger another event.

Any other application may connect to the system and process or reprocess records from a particular topic. The sent data is stored until a predefined retention period has passed. These records are byte arrays, which can store any object in any format. The records have 4 attributes, key and value are compulsory, while timestamp and headers are optional.

Persistency of Memphis{dev}

Memphis{dev} message broker can persist messages on memory or file configured at station level. If you want superior performance, memory is always preferred. For a better option on price point, with near real-time performance, a file-based persistent is always a good choice.

What is message persistence?

The persistent messages are written to the logs and queue data files. When a queue manager is restarted after running into a failure – it recovers the persistent messages as necessary from logged data.

What are the advantages of Memphis{dev) Message Broker?

The Memphis{dev} message broker comes with many benefits that include but is not limited to;

Loose Coupling

This is where a client makes a request and does not have to know about other services, so there is no need to use a discovery mechanism to find the location of the other service instances.

Message Buffering

The brokers are a buffer for messages until they are processed.

Both sides have to be available in synchronous message exchanges over HTTP – The request/response protocol for as long as the conversation takes place.

In Memphis{dev}, message broker is not the case in messaging; the messages are queued and are not processed until the consumer is ready. Take an online store for an example; a store can accept orders even if the ordering services are down or slow as the orders are queued in the message broker and will get processed when the service is up and running again.

Flexible Communication

Memphis{dev} offers more flexible and efficient communication.

Let’s look into some shortcomings of message brokers;

Performance Bottleneck – message brokers, can be a bit of a performance bottleneck. But, modern message brokers like Memphis{dev} are built to offer scalability.

Single Point Failure — Message brokers continuously need to be accessible, but modern message brokers are built for HA.

Added Operational Complexity — message brokers pose as an additional component to an already complex system, a component that needs to be installed, maintained, and configured. Luckily you have stumbled upon the best message broker – the Memphis{dev}, which offers ease, accessibility, easy configuration, and working. Get in touch with us should you have any questions.
