Functions

func MakePath

func MakePath(index string, doc_type string, id string) (string, error)

Types

type Connection

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

type ConnectionPool

type ConnectionPool struct {
	Connections []*Connection

	// options
	Dead_timeout time.Duration
	// contains filtered or unexported fields
}

func (*ConnectionPool) GetConnection

func (pool *ConnectionPool) GetConnection() *Connection

func (*ConnectionPool) MarkDead

func (pool *ConnectionPool) MarkDead(conn *Connection) error

If a connection fails, it will be marked as dead and put on timeout. timeout = default_timeout * 2 ** (fail_count - 1) When the timeout is over, the connection will be resurrected and returned to the live pool

func (*ConnectionPool) MarkLive

func (pool *ConnectionPool) MarkLive(conn *Connection) error

A connection that has been previously marked as dead and succeeds will be marked as live and the dead_count is set to zero

func (*ConnectionPool) SelectRoundRobin

func (pool *ConnectionPool) SelectRoundRobin() *Connection

func (*ConnectionPool) SetConnections

func (pool *ConnectionPool) SetConnections(urls []string, username string, password string) error

func (*ConnectionPool) SetDeadTimeout

func (pool *ConnectionPool) SetDeadTimeout(timeout int)

type Elasticsearch

type Elasticsearch struct {
	MaxRetries int
	// contains filtered or unexported fields
}

func NewElasticsearch

func NewElasticsearch(urls []string, username string, password string) *Elasticsearch

Create a connection to Elasticsearch

func (*Elasticsearch) Bulk

func (es *Elasticsearch) Bulk(index string, doc_type string,
	params map[string]string, body chan interface{}) (*QueryResult, error)

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

func (*Elasticsearch) BulkRequest

func (es *Elasticsearch) BulkRequest(method string, path string,
	params map[string]string, body chan interface{}) ([]byte, error)

Create 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 (*Elasticsearch) CreateIndex

func (es *Elasticsearch) CreateIndex(index string) (*QueryResult, error)

Adds a typed JSON document in a specific index, making it searchable. Implements: <http://www.elastic.co/guide/en/elasticsearch/reference/current/docs-index_.html>

func (*Elasticsearch) Delete

func (es *Elasticsearch) Delete(index string, doc_type string, id string, params map[string]string) (*QueryResult, error)

Deletes a typed JSON document from a specific index based on its id. Implements: http://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete.html

func (*Elasticsearch) Index

func (es *Elasticsearch) Index(index string, doc_type string, id string,
	params map[string]string, body interface{}) (*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 (*Elasticsearch) PerformRequest

func (es *Elasticsearch) PerformRequest(conn *Connection, req *http.Request) ([]byte, bool, error)

Perform the actual request. If the operation was successful, mark it as live and return the response. If it fails, mark it as dead for a period of time. It returns the response, if it should retry sending the request and the error

func (*Elasticsearch) Refresh

func (es *Elasticsearch) Refresh(index string) (*QueryResult, error)

Refresh an index. Call this after doing inserts or creating/deleting indexes in unit tests.

func (*Elasticsearch) Request

func (es *Elasticsearch) Request(method string, path string,
	params map[string]string, body interface{}) ([]byte, error)

Create an HTTP request and send it to Elasticsearch. The request is retransmitted max_retries before returning an error.

func (*Elasticsearch) SearchUri

func (es *Elasticsearch) SearchUri(index string, doc_type string, params map[string]string) (*SearchResults, error)

A search request can be executed purely using a URI by providing request parameters. Implements: http://www.elastic.co/guide/en/elasticsearch/reference/current/search-uri-request.html

func (*Elasticsearch) SetMaxRetries

func (es *Elasticsearch) SetMaxRetries(max_retries int)

type ElasticsearchOutput
