Otto Fowler commented on METRON-1850:
-------------------------------------

There should be some provision on how to handle if the service is down.  If every message has to timeout, then there is going to be issues.

> It would be useful to be able to enrich messages with Stellar using 3rd party (or internal) REST services.  At a minimum this function would:
>  * Stellar function available to GET from an HTTP API
>  * Optional parameters for basic auth (user/password) which generate correct Authorization header
>  * Function returns null value for errors, connection failures etc and logs error
>  * Function must provide and use pooled connection objects at the process level
>  * Function must send Accept: application/json header
>  * A global setting must be available to set a proxy for all API calls, and if present the proxy must be used.
>  * Proxy authentication must also be supported using basic auth.
