Dropwizard Elasticsearch

Build Status Coverage Status Maven Central

A set of classes for using Elasticsearch (version 2.3.0 and higher) in a Dropwizard application.

The package provides a lifecycle-managed client class (ManagedEsClient), a configuration class with the most common options (EsConfiguration), and some health checks which can instantly be used in any Dropwizard application.


Just add EsConfiguration to your Configuration class and create an ManagedEsClient instance in the run method of your service.

You can also add one of the existing health checks to your Environment in the same method. At least the usage of EsClusterHealthCheck is strongly advised.

public class DemoApplication extends Application<DemoConfiguration> {
    // [...]
    public void run(DemoConfiguration config, Environment environment) {
        final ManagedEsClient managedClient = new ManagedEsClient(configuration.getEsConfiguration());
        environment.healthChecks().register("ES cluster health", new EsClusterHealthCheck(managedClient.getClient()));
        // [...]


The following configuration settings are supported by EsConfiguration:

  • nodeClient: When true, ManagedEsClient will create a NodeClient, otherwise a TransportClient; default: true
  • servers: A list of servers for usage with the created TransportClient if nodeClient is false
  • clusterName: The name of the Elasticsearch cluster; default: "elasticsearch"
  • settings: Any additional settings for Elasticsearch, see Configuration
  • settingsFile: Any additional settings file for Elasticsearch, see Configuration

An example configuration file for creating a Node Client could like this:

clusterName: MyClusterName
settings: MyCustomNodeName

The order of precedence is: nodeClient/servers/clusterName > settings > settingsFile, meaning that any setting in settingsFile can be overwritten with settings which in turn get overwritten by the specific settings like clusterName.
