Motivated by Matt's e-mail, I also would like to share my submission for the ApacheCon Europe 2019 <https://aceu19.apachecon.com/>. Fingers crossed...
*How and why of the fastest Log4j JSON layout* Log4j is awesome. Love it or hate it, it is the de facto logger in the Java land. In the era of microservices, where hundreds of applications running on thousands of nodes spitting out logs at rates exceeding gigabytes per second, the output is not an easily navigable text file anymore, but a structured river fed by smaller streams and navigated on giant cruise ship looking dashboards. People further hack this battle tested tools into IoT event streaming pumps with demanding throughput requirements. I will walk you through how bol.com (the biggest e-commerce platform in the Netherlands and Belgium) had a need for a new Log4j JSON layout plugin. I will further explain how people started using it outside bol.com and this motivated it to be the fastest among all its competitors. Enjoy logging? Suffer from JSON battle scars? Have an inclination for garbage-free Java code? Then we have a story you might want to hear.
