What is a database queue?

A queue based database application is an application (or part of one) where multiple users need to work on a pool of records in a queue to process them. The records in the queue are in an “unprocessed” state. One user needs to select or is assigned to one of the records and works with that data.

Why RabbitMQ is better than Kafka?

Kafka is ideal for big data use cases that require the best throughput, while RabbitMQ is ideal for low latency message delivery, guarantees on a per-message basis, and complex routing.

Is RabbitMQ written in Erlang?

Written in Erlang, the RabbitMQ server is built on the Open Telecom Platform framework for clustering and failover. Client libraries to interface with the broker are available for all major programming languages.

Is queue a database?

Queues are interesting databases with interesting concurrency control. It is best to build these mechanisms into a standard database system so other applications can use these interesting features. Queue systems need DBMS functionality.

What is a serial queue?

Serial queues (also known as private dispatch queues) execute one task at a time in the order in which they are added to the queue. Concurrent queues (also known as a type of global dispatch queue) execute one or more tasks concurrently, but tasks are still started in the order in which they were added to the queue.

Is it better to use a database or dedicated MQ?

Database vs Dedicated MQ I am after advice regarding message queueing. We have requirements for “jobs” to be posted to a message queue. The original suggestion was just to use a SQL Server instance and process messages from that. Everything I have read on the internet suggests that using a database for a Message Queue isn’t a scalable solution.

Is it easy to create a message queue in a database?

What’s the difference between MB and MQ messages?

What’s the difference between MQ and TIBCO message queue?

MQ was originally a 1:1 system, indeed a queue to decouple various systems. Tibco by contrast was (sold as a) messaging backbone, where you could have multiple publishers and subscribers on the same topics. Both however (and newer competing products) can play in each other’s space these days.
