Recently Shine Technologies distributed one of its applications using Terracotta, an open-source JVM-level data clustering project.   Terracotta is often used to implement HTTP session replication, as a distributed cache, for transparent POJO Clustering / Spring integration, but can also be used to distribute events (such as tasks in a master/worker grid pattern).  In this case study, Shine Technologies explained how they used Terracotta and the Master Worker pattern to process large volumes of electricity usage data weekly and generate reports with detailed reconciliation & discrepancy highlighting for their customers.

  • We did something similar, but adding routing

    by Mark Turansky,

    I wrote an article about how we built a message bus with TC that includes queuing, routing, splitting, and aggregation (all from Enterprise Integration Patterns). The slickest part is that we've got a pure POJO program that can run in an IDE, but then be distributed (via TC) to dozens on nodes in our production environment.

    The "pure POJO program that can run in an IDE, but then be distributed" thing is the what excites me. That's not one of the benefits that gets trumpeted very loudly, but it's really one of my favorites. It really lets you concentrate on the task at hand instead of fighting with a bunch of exposed infrastructure every time you want to run a test.

    Cheers,
    Orion

    Thank you for this simple yet powerful writeup. Perhaps I have been under a rock for a bit, but Terracotta had just come onto my radar recently and this is exactly what I needed to understand more fully how, when, and where I can use this... thanks again.
