Abstract: You run your SQL-centric infrastructure for 10 years and slowly starting to note you can’t do this way anymore – everything is getting too expensive but your business requires things which are simply impossible without radical cahnges.

This is exact situation we had 2 years before. So we’d like to shouw our experience:

  • Why and how we came into Big Data?
  • Why we choose Apache and Hadoop?
  • What to do and what is already done?
  • What lessans were learned?
  • Hadoop and relational databases: fight or synergy?
  • Reactive Big Data manifest.
