Hi,  
We have a need to enrich the incoming data.  
I’d like to know if I can pull data from another external source as part of an enrichment stage in the pipeline.  
I haven’t identified a core feature for this, but may have missed it.

It may be that I can pull the external data into a cache object and store in Mongo for example, then use as part of my enrichment. The case would either be to add an extra field as part of a standard lookup, or possibly act on the correlation between a stream field and the lookup.

Any ideas or direction would really be appreciated.

Thanks

Brilliant, thanks for the link.  
It looks to be exactly what we need.  
I’ll take it for a spin 🙂
