Configuration # By default, the Table & SQL API is preconfigured for producing accurate results with acceptable performance. Depending on the requirements of a table program, it might be necessary to adjust certain parameters for optimization. For example, unbounded streaming programs may need to ensure that the required state size is capped (see streaming concepts).

Time Attributes # Flink can process data based on different notions of time. Processing time refers to the machine’s system time (also known as epoch time, e.g. Java’s System.currentTimeMillis()) that is executing the respective operation. Event time refers to the processing of streaming data based on timestamps that are attached to each row. The timestamps can encode when an event happened. For more information about time handling in Flink, see the introduction about event time and water...| nightlies.apache.org
