Dropwizard Elasticsearch

========================

[![Build Status](https://travis-ci.org/dropwizard/dropwizard-elasticsearch.svg?branch=master)](https://travis-ci.org/dropwizard/dropwizard-elasticsearch)

[![Coverage Status](https://img.shields.io/coveralls/dropwizard/dropwizard-elasticsearch.svg)](https://coveralls.io/r/dropwizard/dropwizard-elasticsearch)

[![Maven Central](https://img.shields.io/maven-central/v/io.dropwizard.modules/dropwizard-elasticsearch.svg)](http://mvnrepository.com/artifact/io.dropwizard.modules/dropwizard-elasticsearch)

A set of classes for using [Elasticsearch][1] (version 2.3.0 and higher) in a [Dropwizard][2] application.

The package provides a [lifecycle-managed][3] client class (`ManagedEsClient`), a configuration class with the most

common options (`EsConfiguration`), and some [health checks][4] which can instantly be used in any Dropwizard application.

[4]: http://dropwizard.io/1.2.0/docs/manual/core.html#health-checks

Usage

-----

Just add `EsConfiguration` to your [Configuration](http://dropwizard.io/1.2.0/docs/manual/core.html#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](http://dropwizard.io/1.2.0/docs/manual/core.html#environments)

in the same method. At least the usage of `EsClusterHealthCheck` is strongly advised.

```java

public class DemoApplication extends Application {

    // [...]

    @Override

    public void run(DemoConfiguration config, Environment environment) {

        final ManagedEsClient managedClient = new ManagedEsClient(configuration.getEsConfiguration());

        environment.lifecycle().manage(managedClient);

        environment.healthChecks().register("ES cluster health", new EsClusterHealthCheck(managedClient.getClient()));

        // [...]

    }

}

```

Configuration

-------------

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](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/setup-configuration.html)

* `settingsFile`: Any additional settings file for Elasticsearch, see [Configuration](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/setup-configuration.html)

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

```yaml

clusterName: MyClusterName

settings:

  node.name: 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`.
