Synchronous Execution

         '[konserve.core :as k])

(def path "./tmp/rocksdb/konserve")
   
(def store (connect-rocksdb-store db-spec :opts {:sync? true}))

(k/assoc-in store ["foo" :bar] {:foo "baz"} {:sync? true})

(k/exists? store "foo" {:sync? true})

(k/assoc-in store [:bar] 42 {:sync? true})
(k/update-in store [:bar] inc {:sync? true})
(k/get-in store [:bar] nil {:sync? true})
(k/dissoc store :bar {:sync? true})

(k/append store :error-log {:type :horrible} {:sync? true})
(k/log store :error-log {:sync? true})

(let [ba (byte-array (* 10 1024 1024) (byte 42))]
  (time (k/bassoc store "banana" ba {:sync? true})))

(k/bassoc store :binbar (byte-array (range 10)) {:sync? true})

       {:sync? true})
       
(release-rocksdb store)
(delete-rocksdb-store path :opts {:sync? true})
