Tonight, I attended the Java User Group (JUG) Lille meetup, and it was an inspiring session! 🎤✨
A team of a DBA, a Tech Lead, and a Developer/Architect shared their journey of optimizing an information system with 400 batch processes. Their key wins?
⚡ Reducing batch execution time from 19 hours to just 4 hours!
🔄 Smart use of vertical and horizontal scaling
📊 Precalculated tables to optimize repetitive SQL queries
Beyond the talk, I had great conversations with old acquaintances from previous JUG meetups. I also had the chance to chat with one of the organizers about my own journey to becoming a conference speaker—exciting times ahead! 🚀
