Last weekend, the Python Hackathon Düsseldorf took place at trivago’s office. Although we were only five people we had a lot of fun. I took the chance to brush up my Python skills a little bit. Also I wanted to scratch an itch that was bugging me for a long time: our housekeeping book.
You know those bugs, like, those. Where the application state dances around you like a crazed Polynesian fire dancer. Where changing the sorting order of a search in London reverts the result list back to Paris… Seriously? Unfortunately, a lot of us are specialists in dealing with this kind of bug.
Learn how we managed to move fast and create a new Symfony application without breaking our old legacy session handling. We write to our legacy session (which is file based) from our new project which uses PDO as the session storage.
Here at trivago we write a huge number of log messages every day that need to be stored and monitored. To handle all these messages we created Gollum, a tool that enables us to conveniently send messages from multiple sources to different services.
Tackling hard problems is like going on an adventure. Solving a technical challenge feels like finding a hidden treasure. Want to go treasure hunting with us?View all current job openings
For our expandation in the middle east area with our platforms in Israel and United Arab Emirates we had a particularly interesting problem to solve: How do we flip the layout of our page? Your favorite hotel search, trivago, is already available in countries as different as Mexico, South Korea and New Zealand. We are continuously opening new platforms worldwide.
At trivago we love hotels above everything else, but we also like metrics, we love to measure everything, compare, decide, improve and then rinse and repeat. In this blog entry we are going to describe our experience with InfluxDB, a time series database that we are using to store some real time metrics.
