This talk will take the listeners across a practical use case, where I will be showing how I processed more than 11.55M records of LinkedIn Data for candidates to create a RecSys for hiring idealized candidates based on a job description which is bespoke, and create my AI + Human in the loop. I will be showcasing how initially I was stuck in a loop where latency and processing these records in real-time was a problem, and how ClickHouse solved this.
