4. Example

Example1 This API is used to modify the data processing task.

Data processing provides the capacity to filter, clean, mask, enrich, and distribute log data, comparable to the open-source component Logstash. Using the data processing DSL (Domain Specified Language) function, with the underlying layer implemented based on Flink, you can easily process log stream data.
