RabbitMQ provides a web-based user interface (UI) that allows you to manage and monitor the RabbitMQ broker and its components, such as exchanges, queues, and bindings. The RabbitMQ web UI can be accessed using a web browser and provides a user-friendly way to perform common administrative tasks without having to use the command-line tools or … Read more
SSL/TLS encryption in RabbitMQ provides a secure way to transmit messages over a network by encrypting the data in transit. This helps to prevent unauthorized access or eavesdropping on messages being sent between clients and the RabbitMQ broker. Here are the steps to enable SSL/TLS encryption in RabbitMQ: 1. Generate SSL/TLS certificates: You need to … Read more
In RabbitMQ, message compression can be used to reduce the size of messages being sent over the network, which can improve the performance and efficiency of messaging systems, especially when dealing with large messages. There are several ways to implement message compression in RabbitMQ: 1. Compression at the application level: You can compress messages at … Read more
In RabbitMQ, a Dead-Letter Exchange (DLX) is an exchange to which messages are redirected when they cannot be delivered to their intended destination. The DLX allows you to handle messages that have failed to be delivered in a more controlled and efficient way than simply discarding or retrying them indefinitely. Here’s how the Dead-Letter Exchange … Read more
Message priority in RabbitMQ allows you to specify the priority of messages when they are published, so that higher-priority messages are delivered before lower-priority messages. This can be useful in systems where some messages are more important than others and need to be processed more quickly. To use message priority in RabbitMQ, you can set … Read more
Load balancing in RabbitMQ refers to the distribution of message processing across multiple consumers to evenly distribute workload and improve performance and scalability of messaging systems. RabbitMQ supports several load balancing strategies that can be used to distribute messages among multiple consumers. Here are some of the load balancing strategies supported by RabbitMQ: 1. Round-robin: … Read more
Clustering in RabbitMQ allows multiple RabbitMQ nodes to work together as a single logical broker, providing high availability and scalability for messaging systems. In a cluster, each node can share the same data and messages, allowing for seamless failover and load balancing. Here are the steps to set up a RabbitMQ cluster: 1. Install and … Read more
In RabbitMQ, Queue TTL (Time-To-Live) is a feature that allows you to set a time limit on how long a message can remain in a queue before it expires and is automatically removed. Queue TTL is useful for preventing the buildup of stale messages in a queue and for managing resource usage in your messaging … Read more
In RabbitMQ, message persistence refers to the ability to store messages on disk to ensure that they are not lost in the event of a broker or hardware failure. By default, messages are not persisted to disk and are stored in memory, which can result in message loss if the broker crashes or shuts down … Read more
In RabbitMQ, message acknowledgement is used to confirm that a message has been successfully received and processed by a consumer. Message acknowledgement helps to ensure that messages are not lost or duplicated in the system. Here are the two types of message acknowledgement in RabbitMQ: 1. Automatic acknowledgement: In this mode, also known as “auto-ack”, … Read more
