delete-key clj

(delete-key tr key & {:keys [directory] :or {directory *directory*}})

get-range clj

get-val clj

(get-val tr key & {:keys [directory] :or {directory *directory*}})

Get the value for the given key. Accepts the below : :subspace - Subspace to be prefixed :coll - Boolean to indicate if the value needs to be deserialized as collection

(let [fd  (select-api-version 520)
      key "foo"]
(with-open [db (open fd)]
   (tr! db
        (get-val tr key))))
(let [fd    (select-api-version 520)
     key   "foo"
     value [1 2 3]]
(with-open [db (open fd)]
  (tr! db
       (set-val tr key value)
       (get-val tr key) ;; 1
       (get-val tr key :coll true)))) ;; [1 2 3]

key->packed-tuple clj

(key->packed-tuple key)

Pack the key with respect to Tuple encoding

key->tuple clj

(key->tuple key)

Return tuple encoding for the given key

make-range clj

(make-range tr start & {:keys [directory] :or {directory *directory*}})

open clj

(open db cluster)

Initializes networking, connects with the default fdb.cluster file, and opens the database.

set-val clj

(set-val tr key val & {:keys [directory] :or {directory *directory*}})

Set a value for the key. Accepts the below : :subspace - Subspace to be prefixed

(let [fd    (select-api-version 520)
      key   "foo"
      value "bar"]
(with-open [db (open fd)]
   (tr! db
        (set-val tr key value))))

tr! clj macro

(tr! db & actions)

Transaction macro to perform actions. Always use tr for actions inside each action since the transaction variable is bound to tr in the functions.

(let [fd    (select-api-version 520)
      key   "foo"
      value "bar"]
(with-open [db (open fd)]
   (tr! db
        (set-val tr key value)
        (get-val tr key))))

watch! clj

(watch! tr key & {:keys [directory] :or {directory *directory*}})
