• Key Concepts: 
  A keyed stream is a type of stream in SAP Event Stream Processor (ESP) that is used to process data from multiple sources. It is based on a key-value pair, where the key is used to identify the source of the data and the value is the actual data. The keyed stream allows for efficient processing of data from multiple sources, as it can be used to filter out irrelevant data and focus on only the relevant data. 
  
  How to use it: 
  In order to use a keyed stream, you must first define the key-value pair. This can be done by specifying the key and value in the ESP configuration. Once this is done, you can then use the keyed stream to process data from multiple sources. You can also use the keyed stream to filter out irrelevant data and focus on only the relevant data. 
  
  Tips & Tricks: 
  When using a keyed stream, it is important to ensure that the keys are unique and that they are properly defined in the ESP configuration. This will ensure that only relevant data is processed and that irrelevant data is filtered out. Additionally, it is important to ensure that all of the keys are properly defined in order for the keyed stream to work correctly.
