In early 2014, we were faced with a challenge: As our data grew, our current real-time data storage was no longer able to support our growth. We looked for other real-time ingestion systems, and that’s when one of our engineers, Maxime, came across Druid. Let’s backtrack for a minute. The “we” in this story is GumGum, inventors of In-Image Advertising and a leading digital marketing platform based in Santa Monica, the heart of Silicon Beach. The company was founded in 2007, and its data has consistently quadrupled in recent years. We’ve welcomed and embraced this rapid growth, but it’s also kept us in the market for a system that can handle a lot of data.
