For anyone else like me, who has learned Clojure but knows nothing about
Java, you need to convert to a byte array and then use carmine/raw to write
to Redis. So in a let statement I have something like this:
document-as-string (str "{\"transaction-id\" : \"" transaction-id "\",
\"debrief\" : \"" (:debrief document) "\"}" )
document-as-byte-array (bytes (byte-array (map (comp byte int)
document-as-string)))
and then I:
(carmine/wcar redis-connection (carmine/set transaction-id (carmine/raw
document-as-byte-array)))
