This is a preview release of Datahike with FoundationDB as data storage.

Installation

Install FoundationDB for your system.

Usage

(require '[datahike.core :as d])

;; Create an new db
(def db (d/empty-db))

;; Populate the database
(d/db-with db [ { :db/id 1, :name  "Ivan", :age   15 }
                { :db/id 2, :name  "Petr", :age   37 }
                { :db/id 3, :name  "Ivan", :age   37 }
                { :db/id 4, :age 15 }])

;; Search the data
(d/q '[:find  ?e ?v
       :where [?e :name "Ivan"]
              [?e :age ?v]] db)
=> #{[1 15] [3 37]}

Limitations

  • datahike-fdb is not an immutable store, therefore all history related Datahike APIs will not work.
  • Java 8 only.
