At Airbnb, Apache Flink was introduced in 2018 as a supplementary solution for stream processing. It ran alongside Apache Spark™ Streaming for several years before transitioning to become the primary stream processing platform. In this blog post, we will delve into the evolution of Flink architecture at Airbnb and compare our prior Hadoop Yarn platform with the current Kubernetes-based architecture.

In the end we will summarize the impact, learnings along the way and future plans.

Pinterest is a visual discovery platform where people can find ideas like recipes, home and style inspiration, and much more. The platform offers its partners shopping capabilities as well as a significant advertising opportunity with 500+ million monthly active users. Advertisers can purchase ads directly on Pinterest or through partnerships with advertising agencies. Due to our huge scale, advertisers get an opportunity to learn about their Pins and their interaction with Pinterest users from the analytical data. This gives advertisers an opportunity to make decisions which will allow their ads to perform better on our platform.

At Pinterest, real-time insights play a critical role in empowering our advertisers and team members to make data-driven decisions. These decisions impact campaign performance, our experiments’ performance, and our policies such as rules to catch spam. We have been using Druid to store and provide these real-time insights, but as our scale and requirements continue to change, we have been evaluating different storage options. In the end we decided to migrate this data to StarRocks.

In this blog post, we’ll discuss and share our experience of launching our Analytics app on StarRocks. In the past, we have published our thoughts on using Druid and the benefits we have gotten from it. This post highlights the need for a new system as our scale and requirements have changed over time.
