Vert.x ElasticSearch Service

Vert.x 3 elasticsearch service with event bus proxying and RxJava support. Forked from ef-labs/vertx-elasticsearch-service.

The difference to ef-labs/vertx-elasticsearch-service are some additional features and the request and reponse objects are concrete java classes instead of the generic JsonObject.

Configuration

The configuration options are as follows:

{
    "address": <address>,
    "transportAddresses": [ { "hostname": <hostname>, "port": <port> } ],
    "cluster_name": <cluster_name>,
    "client_transport_sniff": <client_transport_sniff>,
    "requireUnits": false
}

address - The event bus address to listen on. (Required)
transportAddresses - An array of transport address objects containing hostname and port. If no transport address are provided the default is "localhost" and 9300
- hostname - the ip or hostname of the node to connect to.
- port - the port of the node to connect to. The default is 9300.
cluster_name - the elastic search cluster name. The default is "elasticsearch".
client_transport_sniff - the client will sniff the rest of the cluster and add those into its list of machines to use. The default is true.
requireUnits - boolean flag whether units are required. The default is false.

An example configuration would be:

{
    "address": "eb.elasticsearch",
    "transportAddresses": [ { "hostname": "host1", "port": 9300 }, { "hostname": "host2", "port": 9301 } ],
    "cluster_name": "my_cluster",
    "client_transport_sniff": true
}

NOTE: No configuration is needed if running elastic search locally with the default cluster name.

Dependency Injection

The DefaultElasticSearchService requires a TransportClientFactory and ElasticSearchConfigurator to be injected.

Default bindings are provided for HK2 and Guice, but you can create your own bindings for your container of choice.

See the englishtown/vertx-hk2 or englishtown/vertx-guice projects for further details.

An example would be:

    // Plain
    final ElasticSearchService elasticSearchService = ElasticSearchService.createEventBusProxy(vertx, "eventbus-address");
    
    elasticSearchService.index("twitter", "tweet", new JsonObject().put("user", "hubrick").put("message", "love elastic search!"), indexResponse -> {
