    fastexcel

    Generate and read big Excel files quickly

    There are not many alternatives when you have to generate xlsx Excel workbooks in Java. The most popular one (Apache POI) includes many features, but when it comes down to huge worksheets it quickly becomes a memory hog.

    Its streaming API may mitigate this problem but it introduces several limitations:

    • Its sliding window mechanism prevents you from accessing cells above the current writing position.
    • It writes stuff to a temporary file.
    • It comes with an overhead on the file size because shared strings are disabled by default. Enabling shared strings is likely to consume much more heap if you deal with string values.

    So, fastexcel has been created to offer an alternative with the following key points:

    • Limited set of features (basic style support, no graph support yet) and very simple API.
    • Reduced memory footprint and high performance by accumulating only necessary elements. XML stuff is piped to the output stream at the end.
    • Multithreading support: each worksheet in the workbook can be generated by a different thread, while fully supporting shared strings and styles.

    brave

    Java distributed tracing implementation compatible with Zipkin backend services.

    Brave is a distributed tracing instrumentation library. Brave typically intercepts production requests to gather timing data, correlate and propagate trace contexts. While typically trace data is sent to Zipkin server, third-party plugins are available to send to alternate services such as Amazon X-Ray.

    This repository includes dependency-free Java libraries and instrumentation for common components used in production services. For example, this includes trace filters for Servlet and log correlation for Apache Log4J.

    You can look at our example project for how to trace a simple web application.

    gitreflow

    Reflow automatically creates pull requests, ensures the code review is approved, and squash merges finished branches to master with a great commit message template.

    Create and switch to new branch nh-branchy-branch:

        $ git reflow start nh-branchy-branch

    Create a pull request for your branch against master or a custom base-branch:

        $ git reflow review

    If your code is approved, merge to base-branch and delete the feature branch:

        $ git reflow deliver
