Prerequisites

edit

If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:
- To use the create action, you must have the create_doc, create, index, or write index privilege. Data streams support only the create action.
- To use the index action, you must have the create, index, or write index privilege.
- To use the delete action, you must have the delete or write index privilege.
- To use the update action, you must have the index or write index privilege.
- To automatically create a data stream or index with a bulk API request, you must have the auto_configure, create_index, or manage index privilege.
- To make the result of a bulk operation visible to search using the refresh parameter, you must have the maintenance or manage index privilege.
Automatic data stream creation requires a matching index template with data stream enabled. See Set up a data stream.

Description

edit

Provides a way to perform multiple index, create, delete, and update actions in a single request.

The actions are specified in the request body using a newline delimited JSON (NDJSON) structure:

action_and_meta_data\n
optional_source\n
action_and_meta_data\n
optional_source\n
....
action_and_meta_data\n
optional_source\n

The index and create actions expect a source on the next line, and have the same semantics as the op_type parameter in the standard index API: create fails if a document with the same ID already exists in the target, index adds or replaces a document as necessary.

Data streams support only the create action. To update or delete a document in a data stream, you must target the backing index containing the document. See Update or delete documents in a backing index.

update expects that the partial doc, upsert, and script and its options are specified on the next line.

delete does not expect a source on the next line and has the same semantics as the standard delete API.

The final line of data must end with a newline character \n. Each newline character may be preceded by a carriage return \r. When sending NDJSON data to the _bulk endpoint, use a Content-Type header of application/json or application/x-ndjson.

Because this format uses literal \n's as delimiters, make sure that the JSON actions and sources are not pretty printed.

If you provide a <target> in the request path, it is used for any actions that don’t explicitly specify an _index argument.

A note on the format: The idea here is to make processing of this as fast as possible. As some of the actions are redirected to other shards on other nodes, only action_meta_data is parsed on the receiving node side.

Client libraries using this protocol should try and strive to do something similar on the client side, and reduce buffering as much as possible.

There is no "correct" number of actions to perform in a single bulk request. Experiment with different settings to find the optimal size for your particular workload.

When using the HTTP API, make sure that the client does not send HTTP chunks, as this will slow things down.

Client support for bulk requests

edit

Some of the officially supported clients provide helpers to assist with bulk requests and reindexing:

Go: See esutil.BulkIndexer
Perl: See Search::Elasticsearch::Client::5_0::Bulk and Search::Elasticsearch::Client::5_0::Scroll
Python: See elasticsearch.helpers.*
JavaScript: See client.helpers.*
.NET: See BulkAllObservable
PHP: See Bulk indexing

Submitting bulk requests with cURL

edit

If you’re providing text file input to curl, you must use the --data-binary flag instead of plain -d. The latter doesn’t preserve newlines. Example:

$ cat requests
{ "index" : { "_index" : "test", "_id" : "1" } }
{ "field1" : "value1" }
$ curl -s -H "Content-Type: application/x-ndjson" -XPOST localhost:9200/_bulk --data-binary "@requests"; echo
{"took":7, "errors": false, "items":[{"index":{"_index":"test","_id":"1","_version":1,"result":"created","forced_refresh":false}}]}

Optimistic concurrency control

edit

Each index and delete action within a bulk API call may include the if_seq_no and if_primary_term parameters in their respective action and meta data lines. The if_seq_no and if_primary_term parameters control how operations are executed, based on the last modification to existing documents. See Optimistic concurrency control for more details.

Versioning

edit

Each bulk item can include the version value using the version field. It automatically follows the behavior of the index / delete operation based on the _version mapping. It also support the version_type (see versioning).

Routing

edit

Each bulk item can include the routing value using the routing field. It automatically follows the behavior of the index / delete operation based on the _routing mapping.

Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.

Wait for active shards

edit

When making bulk calls, you can set the wait_for_active_shards parameter to require a minimum number of shard copies to be active before starting to process the bulk request. See here for further details and a usage example.

Refresh

edit

Control when the changes made by this request are visible to search. See refresh.

Only the shards that receive the bulk request will be affected by refresh. Imagine a _bulk?refresh=wait_for request with three documents in it that happen to be routed to different shards in an index with five shards. The request will only wait for those three shards to refresh. The other two shards that make up the index do not participate in the _bulk request at all.

Security

edit

See URL-based access control.

Path parameters

edit

<target>: (Optional, string) Name of the data stream, index, or index alias to perform bulk actions on.

Query parameters

edit

pipeline

(Optional, string) ID of the pipeline to use to preprocess incoming documents.

refresh

(Optional, enum) If true, Elasticsearch refreshes the affected shards to make this operation visible to search, if wait_for then wait for a refresh to make this operation visible to search, if false do nothing with refreshes. Valid values: true, false, wait_for. Default: false.

require_alias

(Optional, Boolean) If true, the request’s actions must target an index alias. Defaults to false.

routing

(Optional, string) Custom value used to route operations to a specific shard.

_source

(Optional, string) True or false to return the _source field or not, or a list of fields to return.

_source_excludes

(Optional, string) A comma-separated list of source fields to exclude from the response.

You can also use this parameter to exclude fields from the subset specified in _source_includes query parameter.

If the _source parameter is false, this parameter is ignored.

_source_includes

(Optional, string) A comma-separated list of source fields to include in the response.

If this parameter is specified, only these source fields are returned. You can exclude fields from this subset using the _source_excludes query parameter.

If the _source parameter is false, this parameter is ignored.

timeout

(Optional, time units) Period each action waits for the following operations:

Defaults to 1m (one minute). This guarantees Elasticsearch waits for at least the timeout before failing. The actual wait time could be longer, particularly when multiple waits occur.

wait_for_active_shards

(Optional, string) The number of shard copies that must be active before proceeding with the operation. Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). Default: 1, the primary shard.

See Active shards.

Request body

edit

The request body contains a newline-delimited list of create, delete, index, and update actions and their associated source data.

create

(Optional, string) Indexes the specified document if it does not already exist. The following line must contain the source data to be indexed.

_index: (Optional, string) Name of the data stream, index, or index alias to perform the action on. This parameter is required if a <target> is not specified in the request path.
_id: (Optional, string) The document ID. If no ID is specified, a document ID is automatically generated.
require_alias: (Optional, Boolean) If true, the action must target an index alias. Defaults to false.
dynamic_templates: (Optional, map) A map from the full name of fields to the name of dynamic templates. Defaults to an empty map. If a name matches a dynamic template, then that template will be applied regardless of other match predicates defined in the template. And if a field is already defined in the mapping, then this parameter won’t be used.

delete

(Optional, string) Removes the specified document from the index.

_index: (Optional, string) Name of the index or index alias to perform the action on. This parameter is required if a <target> is not specified in the request path.
_id: (Required, string) The document ID.
require_alias: (Optional, Boolean) If true, the action must target an index alias. Defaults to false.

index

(Optional, string) Indexes the specified document. If the document exists, replaces the document and increments the version. The following line must contain the source data to be indexed.

_index: (Optional, string) Name of the index or index alias to perform the action on. This parameter is required if a <target> is not specified in the request path.
_id: (Optional, string) The document ID. If no ID is specified, a document ID is automatically generated.
require_alias: (Optional, Boolean) If true, the action must target an index alias. Defaults to false.
dynamic_templates: (Optional, map) A map from the full name of fields to the name of dynamic templates. Defaults to an empty map. If a name matches a dynamic template, then that template will be applied regardless of other match predicates defined in the template. And if a field is already defined in the mapping, then this parameter won’t be used.

update

(Optional, string) Performs a partial document update. The following line must contain the partial document and update options.

_index: (Optional, string) Name of the index or index alias to perform the action on. This parameter is required if a <target> is not specified in the request path.
_id: (Required, string) The document ID.
require_alias: (Optional, Boolean) If true, the action must target an index alias. Defaults to false.

doc

(Optional, object) The partial document to index. Required for update operations.

<fields>

(Optional, object) The document source to index. Required for create and index operations.

When using the update action, retry_on_conflict can be used as a field in the action itself (not in the extra payload line), to specify how many times an update should be retried in the case of a version conflict.

The update action payload supports the following options: doc (partial document), upsert, doc_as_upsert, script, params (for script), lang (for script), and _source. See update documentation for details on the options. Example with update actions:

$params = [
    'body' => [
        [
            'update' => [
                '_id' => '1',

                'retry_on_conflict' => 3,
            ],
        ],
        [
            'doc' => [
                'field' => 'value',

Because these operations cannot complete successfully, the API returns a response with an errors flag of true.

The response also includes an error object for any failed operations. The error object contains additional information about the failure, such as the error type and reason.

Example with dynamic templates parameter

edit

The below example creates a dynamic template, then performs a bulk request consisting of index/create requests with the dynamic_templates parameter.

PUT my-index/
{
  "mappings": {
    "dynamic_templates": [
      {
        "geo_point": {
             "mapping": {
                "type" : "geo_point"
             }
        }
      }
    ]
  }
}

POST /_bulk
{ "index" : { "_index" : "my_index", "_id" : "1", "dynamic_templates": {"work_location": "geo_point"}} }
{ "field" : "value1", "work_location": "41.12,-71.34", "raw_location": "41.12,-71.34"}
{ "create" : { "_index" : "my_index", "_id" : "2", "dynamic_templates": {"home_location": "geo_point"}} }
{ "field" : "value2", "home_location": "41.12,-71.34"}

The bulk request creates two new fields work_location and home_location with type geo_point according to the dynamic_templates parameter; however, the raw_location field is created using default dynamic mapping rules, as a text field in that case since it is supplied as a string in the JSON document.
