konserve-pg

A PostgreSQL implementation of the konserve kv-protocol on top of HugSQL.

Usage

Add to your leiningen dependencies:

The whole purpose of konserve is to have a unified associative key-value interface for edn datastructures. Just use the standard interface functions of konserve.

You can also provide a DB connection object to the new-pg-store constructor as an argument. We do not require additional settings beyond the konserve serialization protocol for the store, so you can still access the store through PostgreSQL directly wherever you need.

  (require '[konserve-pg.core :refer :all]
           '[konserve.core :as k)
  (def pg-store (<!! (new-pg-store "postgres://postgres:postgres@localhost:5432/konserve")))

  (<!! (k/exists? pg-store  "john"))
  (<!! (k/get-in pg-store ["john"]))
  (<!! (k/assoc-in pg-store ["john"] 42))
  (<!! (k/update-in pg-store ["john"] inc))
  (<!! (k/get-in pg-store ["john"]))

  (defrecord Test [a])
  (<!! (k/assoc-in pg-store ["peter"] (Test. 5)))
  (<!! (k/get-in pg-store ["peter"]))
