Introducing Protector - a Circuit Breaker for Time Series Databases

At trivago we store a subset of our realtime metric data in InfluxDB and we are quite impressed by the load it can handle. Despite all the joy, we had to learn some lessons the hard way. It is pretty easy to overload the database or the web browser by executing queries that return too many datapoints. To prevent that, we wrote Protector - a circuit breaker for Time series databases that blocks malicious queries.

Introducing Gollum: A NxM message multiplexer written in Go

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. While initially only covering log messages Gollum quickly evolved to a routing framework for all kinds of data. This blogpost is a short introduction to Gollum and how we use it at trivago.
