An Open Door to Open Source: Relive our OSS Conference

At trivago, we generate a huge amount of logs and we have our own custom setup for shipping logs using mostly Protocol Buffers. Eventually we end up with some fields in Elasticsearch (ES) that contain partial (or full) URLs. For instance, in our specific case we store the query component of the URL in a field called query and the path component in a field named url_path. Sample values for these fields could be:

trivago Intelligence was born in 2013 with two main objectives: First, to provide bidding capability to the advertisers, who are listed on trivago, and second, to provide them with metrics related to their own hotels; like clicks, revenue, and bookings (typical BI data). This project faced a wave of inevitable data growth which lead to a refactoring process which produced a lot of learnings for the team.
