    PostgreSQL Queue in Java + Spring

    We already discussed about Queue management solutions in the past, and I am always happy to write about it. Queue managers are not easy to implement, and there is a reson if IBM MQ Series is still a successful product. Some month ago, a big bank customer asked me to provide a small queue implementation to increase asynchronous internal processing of our payment solution.

    The project had very strong contraints: I could not use existing queue system because they were not yet available, and I need to be able to provide microservice parallelism in a cloud-environent.

    I have very little time to provide a solid solution, and re-inventing the wheel was not an option. Performance was important, but we plan to have a managable numbers of transactions per seconds, far behind modern cloud database capacity.

    Challenge accepted.

    Complice del passare degli anni, inizio a sviluppare una certa irritazione per alcune soluzioni architetturali chiaramente inutili. Scrivo quindi queste brevi righe a beneficio di qualsiasi giovane sviluppatore Java (o Python o JavaScript o….) affinché prima di “inventarsi” una nuova classe/framework/interfaccia inutile si faccia la triplice Domanda del Destino e cioé:
