Markus Winand - From Backend to Frontend: Why database optimization affects the full stack

It’s one of the long-standing problems of database optimization: how to deliver results in a page wise manner to a web client? The current solutions typically use a flawed approach using offsets. On the one hand, offsets puts a lot of work on the database. But the even more worrying problem is that offsets deliver duplicate results when new data is added. Interestingly, there is another technique which solves both problems at the same time: the so-called key-set pagination is faster than offset is guaranteed to deliver the next results—no duplicates, no missing results. The only downside is that it is not a drop-in replacement—it requires changes through the full technology stack up to the JavaScript doing the AJAX for ‘infinite scrolling’.

Tobias Dreyschultze (SOASTA Inc.) - Olympische Spiele

Zur Vorbereitung für die letzten Olymischen Sommerspiele musste sicher gestellt werden, dass Web und Mobile Applikationen performant und fehlerfrei dem weltweiten Ansturm standhalten. Wie dies mit Hilfe von Cloud Testing Werkzeugen durchgeführt wurde, wird in dieser Session erläutert.
