Talk: From Monolith Database to Microservice Database, and how to improve Application and DB performance in all projects


Q. Tell us a bit about yourself. What are your hobbies and interests?

I work and live in great city of Amsterdam, to which I reallocated from my home town Belgrade. Next to IT, cooking and scuba diving are my passions, and I like to spend time on them.

Number of my interests, and thing that I would like to learn and try, constantly grows. Unfortunately my free time is constantly shrinking. So I am in constant battle between what I want to do, and for what I have time 😉

Q. Why did you select this topic for your session at Voxxed Days Cluj-Napoca 2017? 

While working in Booking.com, I was exposed to working with huge amount of relation databases ( MySQL ) on large scale, with high load traffic with multiple systems.

Working in Booking.com differed in way that there was no stop for pushing code or data into production. What ever you did , you needed to make sure that it can be done on live system, with no downtime or bad performance and errors.

I wanted to share this knowledge and experience with larger audience, since this is something that everyone should know, especially if they are moving into microservices world.


Q. Who should attend your session? 

Anyone who is interested in databases, and systems that work with databases, who is interested into getting better performance from them and who will go from monolith to microservices, and isn’t sure what to do with Database.


Q. What are the key things attendees will take away from your session? 

How to break monolith DB and push it into microservices world.

How to improve performance of any system that use database.

Best practices in dealing with data and high load systems, does and dont’s, and how code need to be modified and changed in order to follow this transition.


Q. Aside from speaking at Voxxed Days Cluj-Napoca 2017, what is the year review look like for you?

This year was interesting and a lot of fun. I gave talks at multiple conferences, JavaOne, Devoxx US, Devovxx PL, Devoxx MA, Voxxed Days Bristol, Voxxed Days Bucharest, Voxxed Days Belgrade, Java Day Istanbul, Java Day Minsk, met a lot of nice people, and also learned a lot in the process.

This was a good year 🙂

Q. What are your plans for the next year?

I am always trying to push the limit, and make everything better than it was last time.
IT Is like a shark, if you stop moving you will die. Next year I hope to speak at even more conferences, to meet even more people and to learn and develop even more in every direction, as husband, father, speaker, manager and engineer of course.
