Event producer
This is the source where the events are happening. These individual events or tuples stringed in continuous never-ending flow actually form the streams of data which are the input source for any NRT application system. These events could be any of the following or more, which are tapped in real-time:
- Application or telecom logs and CDR
- Facebook, Twitter, and other social media
- Data from sensors and satellites
- Videos from CCTV and security cameras
- The format of such data could be image, free text, structured, semi-structured, non-text (audio, video), JSON, XML, and so on
