WebDec 12, 2024 · Flink and Flink SQL support two different notions of time: processing time is the time when an event is being processed (or in other words, the time when your query is being executed), while event time is based on timestamps recorded in the events. How this distinction is reflected in the Table and SQL APIs is described here in the documentation. WebApache Flink provides time values that describe when stream processing events occured, such as Processing Time and Event Time.
