  • 1. I remember when I was in high school and styudying then I prefered to wake up and just read things I wanted to remember. It worked well. Later I understood it was possible because of alpha waves.

    2. Regarding indexes: when you develop etl like system then you know how it is going to be processed. Moreover if you are a database developer then you know which indexes you will need. Of course monitoring is important but we as a team had a dba on board and we discussed performance queries. I learned a lot of dba things.

    3. Fragmentation: if you have a system with indexes not maintained for a couple of years then fragmentation helps. A number of long queries was reduced more than 20x (first monitoring was 1 day, second monitoring was 4 days so technically it is even more).

  • Thanks as always.
    Loved the puffins! In Dutch they’re called “papegaaiduikers”, which translates back to “parrot divers”. Could watch them for hours.

    Next session: in a kayak surrounded by humpback wales? (just kidding, but not entirely 🙂 )
