 # queue-api
 
-generated using Luminus version "2.9.12.25"
+A simple job queue api
 
-FIXME
+## Usage
 
-## Prerequisites
+To run just type
 
-You will need [Leiningen][1] 2.0 or above installed.
+`lein run`
 
-[1]: https://github.com/technomancy/leiningen
+then access [localhost:3000/swagger-ui](http://localhost:3000/swagger-ui/index.html).
 
-## Running
+## Stack
 
-To start a web server for the application, run:
+I chose [luminus](http://www.luminusweb.net/) for my stack as it made the initial setup way easier since it provide a wide range option of configuration for a lot of technologies.
+To bootstrap the project I used `lein new luminus queue-api +swagger +service +kibit` plus datascrypt, which by default doesn't come with Luminus.
 
-    lein run 
+### +Swagger
 
-## License
+When possible I always add it to a project for it make easier to visualize and test endpoints.

+### +Service
+
+To remove all front end stuff since I didn't need it.
+
+### +Kibit
+
+I added because it gives some insight how to make you code more idiomatic.
+
+### Datascript
+
+I chose [datascript](https://github.com/tonsky/datascript) for its easy setup, after little to no effort I had it working.
+Even though it was meant to run on browser it fit nicely in the project, and because it works pretty much like Datomic it has [powerful query system](https://docs.datomic.com/on-prem/query.html) and works seamlessly with clojure.
+Additionally it had an okay [non-documentation](https://github.com/tonsky/datascript/wiki/Getting-started) with some [samples](https://github.com/kristianmandrup/datascript-tutorial) and if I couldn't find for Datascript I would search for a Datomic seeing that query system of both are compatible.  
+
+## Solution
+
+### Data structure
+
+Project has two model:
+
+* Agent
+    * `:agent/id` unique identification of an agent
+    * `:agent/name` agent name
+    * `:agent/primary-skillset`: list of primary skillsets of an agent
+    * `:agent/secondary-skillset` list of secondary skillsets of an agent
+    * `:agent/job` reference to job that the agent is processing
+* Job
+    * `:job/id` unique identification of a job
+    * `:job/status` current status of the job it can be:
+        * `:unassigned` it is waiting to be assigned
+        * `:processing` it is being precessed by an agent
+        * `:completed` it has been done with.
+    * `:job/agent` reference a job that is processing this job or had processed it. it is nil when `:unassigned`
+    * `:job/type` type of the job that it can perform
+    
+Those models wrap up in schema:
+
+```clojure
+{:agent/id                 {:db/unique :db.unique/identity}
+ :agent/primary-skillset   {:db/cardinality :db.cardinality/many}
+ :agent/secondary-skillset {:db/cardinality :db.cardinality/many}
+ :agent/job                {:db.valueType :db.type/ref}
+ :job/id                   {:db/unique :db.unique/identity}
+ :job/agent                {:db.valueType :db.type/ref}}
+```
