This operator enriches tuples with information from the context store. Further Information can be found here. There is also an DBENRICH operator for fetching data from a database or a simple ENRICH that caches incoming streams.

Parameter

• ATTRIBUTES: The attributes from the store object, that should be used for enrichment
• STORE: The name of the store
• OUTER: Enriches with <null>, if the store is empty or (when outer is false) the input is discarded.
  

Example

output = CONTEXTENRICH({store='StoreName', outer='true'}, input)
