Migration tool for Datahike from and to other databases.
Make sure your source and target databases exist. You can run the migration on the commandline:
lein run -s datomic-cloud.edn -t datahike-pg.edn -d datomic-cloud:datahikeUse lein run -- -h for further instructions. See the *-example.edn files for dataomic-cloud and datahike-pg example configurations.
Alternatively open your Clojure project, add io.lambdaforge/wanderung to your dependencies, and start a REPL:
(require '[wanderung.core :as w])
(def datomic-cfg {:name "your-database"
:server-type :ion
:region "eu-west-1"
:system "your-system"
:endpoint "http://entry.your-system.eu-west-1.datomic.net:8182/"
:proxy-port 8182})
(def datahike-cfg {:store {:backend :file
:path "/your-data-path"}
:name "from-datomic"
:schema-flexibility :write
:keep-history? true})
;; if the database doesn't exist, wanderung will create a Datahike database
