Explore a 17-minute conference talk from SREcon25 Americas where Joseph Cirella and Shanthini Velan from Bloomberg explain how they use statistical changepoint detection to identify significant performance changes in Bloomberg's Ticker Plant infrastructure. Learn how this critical system, which delivers real-time market data to internal and external clients, is monitored to prevent latency increases that could impact the company's real-time products. The speakers address implementation challenges including handling "expected" changepoints like market open/close events and downtime, effectively communicating change information to engineers, and establishing productive feedback loops. This presentation offers valuable insights for SRE professionals working with performance-sensitive systems where early detection of regressions is crucial.
