Installing XTDB

XTDB can run in-process, or through traditional client-server connections.

Client/Server

You can start the XTDB server using Docker:

docker pull ghcr.io/xtdb/xtdb-ea

docker run -tip 3000:3000 ghcr.io/xtdb/xtdb-ea

Then, add the thin client to your deps.edn:

;; deps.edn

{:mvn/repos {"ossrh-snapshots" {:url "https://s01.oss.sonatype.org/content/repositories/snapshots"}}

 :deps {org.clojure/clojure {:mvn/version "1.11.1"}
        com.xtdb.labs/xtdb-api {:mvn/version "2.0.0-SNAPSHOT"}
        com.xtdb.labs/xtdb-http-client-clj {:mvn/version "2.0.0-SNAPSHOT"}}}

Once you have a REPL (e.g. by running clj), you can connect to the XTDB node with:

(require '[xtdb.client :as xt.client]
         '[xtdb.api :as xt])

(with-open [node (xt.client/start-client "http://localhost:3000")]
  (xt/status node)

  ;; ...
  )

In process

First, ensure you are running JDK 11+ and then add the XTDB dependencies to your deps.edn:

deps.edn

{:mvn/repos {"ossrh-snapshots" {:url "https://s01.oss.sonatype.org/content/repositories/snapshots"}}

 :deps {org.clojure/clojure {:mvn/version "1.11.1"}
        com.xtdb.labs/xtdb-api {:mvn/version "2.0.0-SNAPSHOT"}
        com.xtdb.labs/xtdb-core {:mvn/version "2.0.0-SNAPSHOT"}}

 ;; needed on JDK16+
 :aliases {:xtdb {:jvm-opts ["--add-opens=java.base/java.nio=ALL-UNNAMED"
                             "-Dio.netty.tryReflectionSetAccessible=true"]}}}

Once you have a REPL (started with clj -A:xtdb if you’re on JDK 16+), you can create an in-memory XTDB node with:

(require '[xtdb.node :as xt.node]
         '[xtdb.api :as xt])

(with-open [node (xt.node/start-node {})]
  (xt/status node)

  ;; ...
  )
