UtcClockProvider must be used to support multiple time zones. If UtcClockProvider is used, all date values are stored in UTC and sent to the client in UTC format, then, we can convert the UTC date to the user's time zone through the user's current time zone settings on the client.

generally a combination of simple events. However, a simple Data Stream Management System (DSMs) can only process filtering and aggregation of simple events, the concept of complex events is not supported. Therefore, it is necessary to build a Complex Event Processing System (CEP) on the data stream to meet such requirements. Because domain practice is the result of years of experience in a specific business unit, it is difficult to expect a single s

Each Flink program relies on a set of Flink libraries.
The Flink itself consists of a set of classes and dependencies that are required to run. The combination of all classes and dependencies forms the core of the Flink runtime and must exist when a Flink program runs.
These core classes and dependencies are packaged into flink-dist. jars.
In order to avoid excessive dependencies and classes in Classpath by default, the Flink core dependency does not contain any connectors or libraries

trying to challenge this conclusion, interested comrades please see for yourself. On the other hand, people have doubts about the traditional CEP solution, and think that its non distributed architecture is not scalable enough to scaleout to meet the massive data processing requirements. This time, Yahoo! S4 and Twitter storm just scratched people's itch.
