This article delves into the complexities of managing state in Structured Streaming queries, particularly focusing on the critical role of watermarks in preventing unbounded growth of state stores. When watermarks are misconfigured, the checkpoint mechanism, intended for recovery, can instead become the source of a major incident, as illustrated by a real-world scenario where a 146GB checkpoint led to a fraud detection pipeline falling significantly behind. The piece highlights how such issues can cripple real-time data processing and emphasizes the need for careful configuration and monitoring of state management in streaming applications. AI
