Types

type BulkResult

type BulkResult struct {
	Items []json.RawMessage `json:"items"`
}

type Client

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

func NewClient

func NewClient(
	url, index string, tls *tls.Config,
	username, password string,
) *Client

func (*Client) Clone

func (client *Client) Clone() *Client

func (*Client) PublishEvent

func (client *Client) PublishEvent(event common.MapStr) error

func (*Client) PublishEvents

func (client *Client) PublishEvents(
	events []common.MapStr,
) ([]common.MapStr, error)

PublishEvents sends all events to elasticsearch. On error a slice with all events not published or confirmed to be processed by elasticsearch will be returned. The input slice backing memory will be reused by return the value.

type Connection

type Connection struct {
	URL      string
	Username string
	Password string
	// contains filtered or unexported fields
}

func (*Connection) Bulk

func (conn *Connection) Bulk(
	index, docType string,
	params map[string]string, body []interface{},
) (*QueryResult, error)

Bulk performs many index/delete operations in a single API call. Implements: http://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html

func (*Connection) BulkWith

func (conn *Connection) BulkWith(
	index string,
	docType string,
	params map[string]string,
	metaBuilder MetaBuilder,
	body []interface{},
) (*QueryResult, error)

BulkWith creates a HTTP request containing a bunch of operations and send them to Elasticsearch. The request is retransmitted up to max_retries before returning an error.

func (*Connection) Close

func (conn *Connection) Close() error

func (*Connection) Connect

func (conn *Connection) Connect(timeout time.Duration) error

func (*Connection) CountSearchURI

func (es *Connection) CountSearchURI(
	index string, docType string,
	params map[string]string,
) (int, *CountResults, error)

func (*Connection) CreateIndex

func (es *Connection) CreateIndex(index string, body interface{}) (int, *QueryResult, error)

CreateIndex creates a new index, optionally with settings and mappings passed in the body. Implements: https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html

func (*Connection) Delete

func (es *Connection) Delete(index string, docType string, id string, params map[string]string) (int, *QueryResult, error)

func (*Connection) Index

func (es *Connection) Index(
	index, docType, id string,
	params map[string]string,
	body interface{},
) (int, *QueryResult, error)

Index adds or updates a typed JSON document in a specified index, making it searchable. In case id is empty, a new id is created over a HTTP POST request. Otherwise, a HTTP PUT request is issued. Implements: http://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html

func (*Connection) IsConnected

func (conn *Connection) IsConnected() bool

func (*Connection) Ping

func (conn *Connection) Ping(timeout time.Duration) (bool, error)

func (*Connection) Refresh
