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))) On Wednesday, July 8, 2015 at 4:44:16 PM UTC-4, gingers...@gmail.com wrote: > > Ah, I just saw this, which might help me: > > https://github.com/ptaoussanis/carmine/issues/83 > > > On Wednesday, July 8, 2015 at 4:35:49 PM UTC-4, gingers...@gmail.com > wrote: >> >> >> I am not sure if this is a Clojure question or a Java question.
