Clojurians Log v2

Naw, I appreciate any opinions and insights. My goal is just educate myself of the options available and their pros and cons.

I would use the Jackdaw EDN serde until you need something better.

I have a question around error reporting for schema coercion:

(def +registry+
 (merge jav/+base-schema-type-registry+
        jav/+UUID-type-registry+))

(def schema-type
  (jav/make-coercion-stack
   +registry+))

(defn parse-schema [clj-schema]
  (.parse (Schema$Parser.) ^String (json/write-str clj-schema)))

(def person-schema
  {:type "record"
   :name "PersonSchema"
   :fields [{:type [{:type "record"
                     :name "value"
                     :fields [{:type "long" :name "age"}]}]
             :name "person"}]})

(jav/clj->avro (schema-type (parse-schema person-schema)) {:person {}} []) --> throws an ExceptionInfo clojure.lang.PersistentArrayMap is not a valid type for union [RECORD]  clojure.core/ex-info (core.clj:4739)

(def person-schema-no-union
  {:type "record"
   :name "PersonSchema"
   :fields [{:type {:type "record"
                    :name "value"
                    :fields [{:type "long" :name "age"}]}
             :name "person"}]})

(jav/clj->avro (schema-type (parse-schema person-schema)) {:person {}} []) --> throws an AvroRuntimeException Field age type:LONG pos:0 not set and has no default value  org.apache.avro.generic.GenericData.getDefaultValue (GenericData.java:984)
