Elastic

Elastic is an Elasticsearch client for the Go programming language.

Build Status Godoc license

See the wiki for additional information about Elastic.

Releases

The release branches (e.g. release-branch.v5) are actively being worked on and can break at any time. If you want to use stable versions of Elastic, please use the packages released via gopkg.in.

Here's the version matrix:

Elasticsearch version Elastic version - Package URL
5.x 5.0 gopkg.in/olivere/elastic.v5 (source doc)
2.x 3.0 gopkg.in/olivere/elastic.v3 (source doc)
1.x 2.0 gopkg.in/olivere/elastic.v2 (source doc)
0.9-1.3 1.0 gopkg.in/olivere/elastic.v1 (source doc)

Example:

You have installed Elasticsearch 5.0.0 and want to use Elastic. As listed above, you should use Elastic 5.0. So you first install the stable release of Elastic 5.0 from gopkg.in.

$ go get gopkg.in/olivere/elastic.v5

You then import it with this import path:

import elastic "gopkg.in/olivere/elastic.v5"
Elastic 5.0

Elastic 5.0 targets Elasticsearch 5.0.0 and later. Elasticsearch 5.0.0 was released on 26th October 2016.

Notice that there are will be a lot of breaking changes in Elasticsearch 5.0 and we used this as an opportunity to clean up and refactor Elastic as we did in the transition from Elastic 2.0 (for Elasticsearch 1.x) to Elastic 3.0 (for Elasticsearch 2.x).

Furthermore, the jump in version numbers will give us a chance to be in sync with the Elastic Stack.

Elastic 3.0

Elastic 3.0 targets Elasticsearch 2.x and is published via gopkg.in/olivere/elastic.v3.

Elastic 3.0 will only get critical bug fixes. You should update to a recent version.

Elastic 2.0

Elastic 2.0 targets Elasticsearch 1.x and is published via gopkg.in/olivere/elastic.v2.

Elastic 2.0 will only get critical bug fixes. You should update to a recent version.

Elastic 1.0

Elastic 1.0 is deprecated. You should really update Elasticsearch and Elastic to a recent version.

However, if you cannot update for some reason, don't worry. Version 1.0 is still available. All you need to do is go-get it and change your import path as described above.

Status

We use Elastic in production since 2012. Elastic is stable but the API changes now and then. We strive for API compatibility. However, Elasticsearch sometimes introduces breaking changes and we sometimes have to adapt.

Having said that, there have been no big API changes that required you to rewrite your application big time. More often than not it's renaming APIs and adding/removing features so that Elastic is in sync with Elasticsearch.

Elastic has been used in production with the following Elasticsearch versions: 0.90, 1.0-1.7, and 2.0-2.4.1. Furthermore, we use Travis CI to test Elastic with the most recent versions of Elasticsearch and Go. See the .travis.yml file for the exact matrix and Travis for the results.

Elasticsearch has quite a few features. Most of them are implemented by Elastic. I add features and APIs as required. It's straightforward to implement missing pieces. I'm accepting pull requests :-)

Having said that, I hope you find the project useful.

Getting Started

The first thing you do is to create a Client. The client connects to Elasticsearch on http://127.0.0.1:9200 by default.

You typically create one client for your app. Here's a complete example of creating a client, creating an index, adding a document, executing a search etc.

// Create a context
ctx := context.Background()

// Create a client
client, err := elastic.NewClient()
if err != nil {
    // Handle error
}

// Create an index
_, err = client.CreateIndex("twitter").Do(ctx)
if err != nil {
    // Handle error
    panic(err)
}

// Add a document to the index
tweet := Tweet{User: "olivere", Message: "Take Five"}
_, err = client.Index().
    Index("twitter").
    Type("tweet").
    Id("1").
    BodyJson(tweet).
    Refresh(true).
    Do(ctx)
if err != nil {
    // Handle error
    panic(err)
}

// Search with a term query
termQuery := elastic.NewTermQuery("user", "olivere")
searchResult, err := client.Search().
    Index("twitter").   // search in index "twitter"
    Query(termQuery).   // specify the query
    Sort("user", true). // sort by "user" field, ascending
    From(0).Size(10).   // take documents 0-9
    Pretty(true).       // pretty print request and response JSON
    Do(ctx)             // execute
if err != nil {
    // Handle error
    panic(err)
}

// searchResult is of type SearchResult and returns hits, suggestions,
// and all kinds of other information from Elasticsearch.
fmt.Printf("Query took %d milliseconds\n", searchResult.TookInMillis)

// Each is a convenience function that iterates over hits in a search result.
// It makes sure you don't need to check for nil values in the response.
// However, it ignores errors in serialization. If you want full control
// over iterating the hits, see below.
var ttyp Tweet
for _, item := range searchResult.Each(reflect.TypeOf(ttyp)) {
    if t, ok := item.(Tweet); ok {
        fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
    }
}
// TotalHits is another convenience function that works even when something goes wrong.
fmt.Printf("Found a total of %d tweets\n", searchResult.TotalHits())

// Here's how you iterate through results with full control over each step.
if searchResult.Hits.TotalHits > 0 {
    fmt.Printf("Found a total of %d tweets\n", searchResult.Hits.TotalHits)

    // Iterate through results
    for _, hit := range searchResult.Hits.Hits {
        // hit.Index contains the name of the index

        // Deserialize hit.Source into a Tweet (could also be just a map[string]interface{}).
        var t Tweet
        err := json.Unmarshal(*hit.Source, &t)
        if err != nil {
            // Deserialization failed
        }

        // Work with tweet
        fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
    }
} else {
    // No hits
    fmt.Print("Found no tweets\n")
}

// Delete the index again
_, err = client.DeleteIndex("twitter").Do(ctx)
if err != nil {
    // Handle error
    panic(err)
}

Here's a link to a complete working example.

Documentation

Overview

Package elastic provides an interface to the Elasticsearch server (http://www.elasticsearch.org/).

The first thing you do is to create a Client. If you have Elasticsearch installed and running with its default settings (i.e. available at http://127.0.0.1:9200), all you need to do is:

client, err := elastic.NewClient()
if err != nil {
	// Handle error
}

If your Elasticsearch server is running on a different IP and/or port, just provide a URL to NewClient:

// Create a client and connect to http://192.168.2.10:9201
client, err := elastic.NewClient(elastic.SetURL("http://192.168.2.10:9201"))
if err != nil {
  // Handle error
}

You can pass many more configuration parameters to NewClient. Review the documentation of NewClient for more information.

If no Elasticsearch server is available, services will fail when creating a new request and will return ErrNoClient.

A Client provides services. The services usually come with a variety of methods to prepare the query and a Do function to execute it against the Elasticsearch REST interface and return a response. Here is an example of the IndexExists service that checks if a given index already exists.

exists, err := client.IndexExists("twitter").Do(context.Background())
if err != nil {
	// Handle error
}
if !exists {
	// Index does not exist yet.
}

Look up the documentation for Client to get an idea of the services provided and what kinds of responses you get when executing the Do function of a service. Also see the wiki on Github for more details.

Functions

func IsNotFound

func IsNotFound(err interface{}) bool

IsNotFound returns true if the given error indicates that Elasticsearch returned HTTP status 404. The err parameter can be of type *elastic.Error, elastic.Error, *http.Response or int (indicating the HTTP status code).

func IsTimeout

func IsTimeout(err interface{}) bool

IsTimeout returns true if the given error indicates that Elasticsearch returned HTTP status 408. The err parameter can be of type *elastic.Error, elastic.Error, *http.Response or int (indicating the HTTP status code).

Types

type AcknowledgedResponse

type AcknowledgedResponse struct {
	Acknowledged bool `json:"acknowledged"`
}

AcknowledgedResponse is returned from various APIs. It simply indicates whether the operation is ack'd or not.

type Aggregation

type Aggregation interface {
	// Source returns a JSON-serializable aggregation that is a fragment
	// of the request sent to Elasticsearch.
	Source() (interface{}, error)
}

Aggregations can be seen as a unit-of-work that build analytic information over a set of documents. It is (in many senses) the follow-up of facets in Elasticsearch. For more details about aggregations, visit: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations.html

type AggregationBucketFilters

type AggregationBucketFilters struct {
	Aggregations

	Buckets      []*AggregationBucketKeyItem          //`json:"buckets"`
	NamedBuckets map[string]*AggregationBucketKeyItem //`json:"buckets"`
	Meta         map[string]interface{}               // `json:"meta,omitempty"`
}

AggregationBucketFilters is a multi-bucket aggregation that is returned with a filters aggregation.

func (*AggregationBucketFilters) UnmarshalJSON

func (a *AggregationBucketFilters) UnmarshalJSON(data []byte) error

It allows setting policies when to flush new bulk requests, e.g. based on a number of actions, on the size of the actions, and/or to flush periodically. It also allows to control the number of concurrent bulk requests allowed to be executed in parallel.

BulkProcessorService, by default, commits either every 1000 requests or when the (estimated) size of the bulk requests exceeds 5 MB. However, it does not commit periodically. BulkProcessorService also does retry by default, using an exponential backoff algorithm.

The caller is responsible for setting the index and type on every bulk request added to BulkProcessorService.

BulkProcessorService takes ideas from the BulkProcessor of the Elasticsearch Java API as documented in https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-docs-bulk-processor.html.

You can interoperate with the BulkProcessor returned by Do, e.g. Start and Stop (or Close) it.

Calling Do several times returns new BulkProcessors. You probably don't want to do this. BulkProcessorService implements just a builder pattern.

func (*BulkProcessorService) FlushInterval

func (s *BulkProcessorService) FlushInterval(interval time.Duration) *BulkProcessorService

FlushInterval specifies when to flush at the end of the given interval. This is disabled by default. If you want the bulk processor to operate completely asynchronously, set both BulkActions and BulkSize to -1 and set the FlushInterval to a meaningful interval.

type BulkProcessorWorkerStats

type BulkProcessorWorkerStats struct {
	Queued       int64         // # of requests queued in this worker
	LastDuration time.Duration // duration of last commit
}

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client is an Elasticsearch client. Create one by calling NewClient.

func NewClient

func NewClient(options ...ClientOptionFunc) (*Client, error)

NewClient creates a new client to work with Elasticsearch.

NewClient, by default, is meant to be long-lived and shared across your application. If you need a short-lived client, e.g. for request-scope, consider using NewSimpleClient instead.

The caller can configure the new client by passing configuration options to the func.

Example:

client, err := elastic.NewClient(
  elastic.SetURL("http://127.0.0.1:9200", "http://127.0.0.1:9201"),
  elastic.SetBasicAuth("user", "secret"))

If no URL is configured, Elastic uses DefaultURL by default.

If the sniffer is enabled (the default), the new client then sniffes the cluster via the Nodes Info API (see http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-nodes-info.html#cluster-nodes-info). It uses the URLs specified by the caller. The caller is responsible to only pass a list of URLs of nodes that belong to the same cluster. This sniffing process is run on startup and periodically. Use SnifferInterval to set the interval between two sniffs (default is 15 minutes). In other words: By default, the client will find new nodes in the cluster and remove those that are no longer available every 15 minutes. Disable the sniffer by passing SetSniff(false) to NewClient.

The list of nodes found in the sniffing process will be used to make connections to the REST API of Elasticsearch. These nodes are also periodically checked in a shorter time frame. This process is called a health check. By default, a health check is done every 60 seconds. You can set a shorter or longer interval by SetHealthcheckInterval. Disabling health checks is not recommended, but can be done by SetHealthcheck(false).

Connections are automatically marked as dead or healthy while making requests to Elasticsearch. When a request fails, Elastic will call into the Retry strategy which can be specified with SetRetry. The Retry strategy is also responsible for handling backoff i.e. the time to wait before starting the next request. There are various standard backoff implementations, e.g. ExponentialBackoff or SimpleBackoff. Retries are disabled by default.

If no HttpClient is configured, then http.DefaultClient is used. You can use your own http.Client with some http.Transport for advanced scenarios.

An error is also returned when some configuration option is invalid or the new client cannot sniff the cluster (if enabled).

func NewSimpleClient

func NewSimpleClient(options ...ClientOptionFunc) (*Client, error)

NewSimpleClient creates a new short-lived Client that can be used in use cases where you need e.g. one client per request.

While NewClient by default sets up e.g. periodic health checks and sniffing for new nodes in separate goroutines, NewSimpleClient does not and is meant as a simple replacement where you don't need all the heavy lifting of NewClient.

NewSimpleClient does the following by default: First, all health checks are disabled, including timeouts and periodic checks. Second, sniffing is disabled, including timeouts and periodic checks. The number of retries is set to 1. NewSimpleClient also does not start any goroutines.

Notice that you can still override settings by passing additional options, just like with NewClient.

type ClusterStateService

type ClusterStateService struct {
	// contains filtered or unexported fields
}

ClusterStateService allows to get a comprehensive state information of the whole cluster.

See https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-state.html for details.

Example
package main

import (
	"fmt"

	"golang.org/x/net/context"

	elastic "gopkg.in/olivere/elastic.v5"
)

func main() {
	client, err := elastic.NewClient()
	if err != nil {
		panic(err)
	}

	// Get cluster state
	res, err := client.ClusterState().Metric("version").Do(context.Background())
	if err != nil {
		panic(err)
	}
	fmt.Printf("Cluster %q has version %d", res.ClusterName, res.Version)
