Create index API
editCreate index API
editCreates a new index.
resp = client.indices.create( index="my-index-000001", ) print(resp)
response = client.indices.create( index: 'my-index-000001' ) puts response
const response = await client.indices.create({ index: "my-index-000001", }); console.log(response);
PUT /my-index-000001
Request
editPUT /<index>
Prerequisites
edit-
If the Elasticsearch security features are enabled, you must have the
create_index
ormanage
index privilege for the target index. To add the index to an alias, you must have themanage
index privilege for the alias.
Description
editYou can use the create index API to add a new index to an Elasticsearch cluster. When creating an index, you can specify the following:
- Settings for the index
- Mappings for fields in the index
- Index aliases
Path parameters
edit-
<index>
-
(Required, string) Name of the index you wish to create.
Index names must meet the following criteria:
- Lowercase only
-
Cannot include
\
,/
,*
,?
,"
,<
,>
,|
, ` ` (space character),,
,#
-
Indices prior to 7.0 could contain a colon (
:
), but that’s been deprecated and won’t be supported in 7.0+ -
Cannot start with
-
,_
,+
-
Cannot be
.
or..
- Cannot be longer than 255 bytes (note it is bytes, so multi-byte characters will count towards the 255 limit faster)
-
Names starting with
.
are deprecated, except for hidden indices and internal indices managed by plugins
Query parameters
edit-
wait_for_active_shards
-
(Optional, string) The number of copies of each shard that must be active before proceeding with the operation. Set to
all
or any non-negative integer up to the total number of copies of each shard in the index (number_of_replicas+1
). Defaults to1
, meaning to wait just for each primary shard to be active.See Active shards.
-
master_timeout
-
(Optional, time units)
Period to wait for the master node. If the master node is not available before
the timeout expires, the request fails and returns an error. Defaults to
30s
. Can also be set to-1
to indicate that the request should never timeout. -
timeout
-
(Optional, time units) Period to wait for a response from all relevant nodes in the cluster after updating the cluster metadata.
If no response is received before the timeout expires, the cluster metadata update still applies but the response will indicate that it was not completely acknowledged.
Defaults to
30s
. Can also be set to-1
to indicate that the request should never timeout.
Request body
edit-
aliases
-
(Optional, object of objects) Aliases for the index.
Properties of
aliases
objects-
<alias>
-
(Required, object) The key is the alias name. Index alias names support date math.
The object body contains options for the alias. Supports an empty object.
Properties of
<alias>
-
filter
- (Optional, Query DSL object) Query used to limit documents the alias can access.
-
index_routing
-
(Optional, string) Value used to route indexing operations to a specific shard.
If specified, this overwrites the
routing
value for indexing operations. -
is_hidden
-
(Optional, Boolean) If
true
, the alias is hidden. Defaults tofalse
. All indices for the alias must have the sameis_hidden
value. -
is_write_index
-
(Optional, Boolean) If
true
, the index is the write index for the alias. Defaults tofalse
. -
routing
- (Optional, string) Value used to route indexing and search operations to a specific shard.
-
search_routing
-
(Optional, string) Value used to route search operations to a specific shard. If
specified, this overwrites the
routing
value for search operations.
-
-
-
mappings
-
(Optional, mapping object) Mapping for fields in the index. If specified, this mapping can include:
- Field names
- Field data types
- Mapping parameters
See Mapping.
-
settings
- (Optional, index setting object) Configuration options for the index. See Index settings.
Examples
editIndex settings
editEach index created can have specific settings associated with it, defined in the body:
resp = client.indices.create( index="my-index-000001", settings={ "index": { "number_of_shards": 3, "number_of_replicas": 2 } }, ) print(resp)
response = client.indices.create( index: 'my-index-000001', body: { settings: { index: { number_of_shards: 3, number_of_replicas: 2 } } } ) puts response
const response = await client.indices.create({ index: "my-index-000001", settings: { index: { number_of_shards: 3, number_of_replicas: 2, }, }, }); console.log(response);
PUT /my-index-000001 { "settings": { "index": { "number_of_shards": 3, "number_of_replicas": 2 } } }
Default for |
|
Default for |
or more simplified
resp = client.indices.create( index="my-index-000001", settings={ "number_of_shards": 3, "number_of_replicas": 2 }, ) print(resp)
response = client.indices.create( index: 'my-index-000001', body: { settings: { number_of_shards: 3, number_of_replicas: 2 } } ) puts response
const response = await client.indices.create({ index: "my-index-000001", settings: { number_of_shards: 3, number_of_replicas: 2, }, }); console.log(response);
PUT /my-index-000001 { "settings": { "number_of_shards": 3, "number_of_replicas": 2 } }
You do not have to explicitly specify index
section inside the
settings
section.
For more information regarding all the different index level settings that can be set when creating an index, please check the index modules section.
Mappings
editThe create index API allows for providing a mapping definition:
resp = client.indices.create( index="test", settings={ "number_of_shards": 1 }, mappings={ "properties": { "field1": { "type": "text" } } }, ) print(resp)
response = client.indices.create( index: 'test', body: { settings: { number_of_shards: 1 }, mappings: { properties: { "field1": { type: 'text' } } } } ) puts response
res, err := es.Indices.Create( "test", es.Indices.Create.WithBody(strings.NewReader(`{ "settings": { "number_of_shards": 1 }, "mappings": { "properties": { "field1": { "type": "text" } } } }`)), ) fmt.Println(res, err)
const response = await client.indices.create({ index: "test", settings: { number_of_shards: 1, }, mappings: { properties: { field1: { type: "text", }, }, }, }); console.log(response);
PUT /test { "settings": { "number_of_shards": 1 }, "mappings": { "properties": { "field1": { "type": "text" } } } }
Aliases
editThe create index API allows also to provide a set of aliases:
resp = client.indices.create( index="test", aliases={ "alias_1": {}, "alias_2": { "filter": { "term": { "user.id": "kimchy" } }, "routing": "shard-1" } }, ) print(resp)
response = client.indices.create( index: 'test', body: { aliases: { "alias_1": {}, "alias_2": { filter: { term: { 'user.id' => 'kimchy' } }, routing: 'shard-1' } } } ) puts response
const response = await client.indices.create({ index: "test", aliases: { alias_1: {}, alias_2: { filter: { term: { "user.id": "kimchy", }, }, routing: "shard-1", }, }, }); console.log(response);
PUT /test { "aliases": { "alias_1": {}, "alias_2": { "filter": { "term": { "user.id": "kimchy" } }, "routing": "shard-1" } } }
Index alias names also support date math.
resp = client.indices.create( index="logs", aliases={ "<logs_{now/M}>": {} }, ) print(resp)
response = client.indices.create( index: 'logs', body: { aliases: { "<logs_{now/M}>": {} } } ) puts response
const response = await client.indices.create({ index: "logs", aliases: { "<logs_{now/M}>": {}, }, }); console.log(response);
PUT /logs { "aliases": { "<logs_{now/M}>": {} } }
Wait for active shards
editBy default, index creation will only return a response to the client when the primary copies of each shard have been started, or the request times out. The index creation response will indicate what happened:
{ "acknowledged": true, "shards_acknowledged": true, "index": "logs" }
acknowledged
indicates whether the index was successfully created in the cluster, while
shards_acknowledged
indicates whether the requisite number of shard copies were started for
each shard in the index before timing out. Note that it is still possible for either
acknowledged
or shards_acknowledged
to be false
, but the index creation was successful.
These values simply indicate whether the operation completed before the timeout. If
acknowledged
is false
, then we timed out before the cluster state was updated with the
newly created index, but it probably will be created sometime soon. If shards_acknowledged
is false
, then we timed out before the requisite number of shards were started (by default
just the primaries), even if the cluster state was successfully updated to reflect the newly
created index (i.e. acknowledged=true
).
We can change the default of only waiting for the primary shards to start through the index
setting index.write.wait_for_active_shards
(note that changing this setting will also affect
the wait_for_active_shards
value on all subsequent write operations):
resp = client.indices.create( index="test", settings={ "index.write.wait_for_active_shards": "2" }, ) print(resp)
response = client.indices.create( index: 'test', body: { settings: { 'index.write.wait_for_active_shards' => '2' } } ) puts response
res, err := es.Indices.Create( "test", es.Indices.Create.WithBody(strings.NewReader(`{ "settings": { "index.write.wait_for_active_shards": "2" } }`)), ) fmt.Println(res, err)
const response = await client.indices.create({ index: "test", settings: { "index.write.wait_for_active_shards": "2", }, }); console.log(response);
PUT /test { "settings": { "index.write.wait_for_active_shards": "2" } }
or through the request parameter wait_for_active_shards
:
$params = [ 'index' => 'test', ]; $response = $client->indices()->create($params);
resp = client.indices.create( index="test", wait_for_active_shards="2", ) print(resp)
response = client.indices.create( index: 'test', wait_for_active_shards: 2 ) puts response
res, err := es.Indices.Create("test?wait_for_active_shards=2") fmt.Println(res, err)
const response = await client.indices.create({ index: "test", wait_for_active_shards: 2, }); console.log(response);
PUT /test?wait_for_active_shards=2
