Create or update mappings
Introduced 1.0
If you want to create or add mappings and fields to an index, you can use the put mapping API operation. For an existing mapping, this operation updates the mapping.
You can’t use this operation to update mappings that already map to existing data in the index. You must first create a new index with your desired mappings, and then use the reindex API operation to map all the documents from your old index to the new index. If you don’t want any downtime while you re-index your indexes, you can use aliases.
Required path parameter
The only required path parameter is the index with which to associate the mapping. If you don’t specify an index, you will get an error. You can specify a single index, or multiple indexes separated by a comma as follows:
PUT /<target-index>/_mapping
PUT /<target-index1>,<target-index2>/_mapping
Required request body field
The request body must contain properties
, which has all of the mappings that you want to create or update.
{
"properties":{
"color":{
"type": "text"
},
"year":{
"type": "integer"
}
}
}
Optional query parameters
Optionally, you can add query parameters to make a more specific request. For example, to skip any missing or closed indexes in the response, you can add the ignore_unavailable
query parameter to your request as follows:
PUT /sample-index/_mapping?ignore_unavailable
The following table defines the put mapping query parameters:
Parameter | Data type | Description |
---|---|---|
allow_no_indices | Boolean | Whether to ignore wildcards that don’t match any indexes. Default is true . |
expand_wildcards | String | Expands wildcard expressions to different indexes. Combine multiple values with commas. Available values are all (match all indexes), open (match open indexes), closed (match closed indexes), hidden (match hidden indexes), and none (do not accept wildcard expressions), which must be used with open , closed , or both. Default is open . |
ignore_unavailable | Boolean | If true, OpenSearch does not include missing or closed indexes in the response. |
cluster_manager_timeout | Time | How long to wait for a connection to the cluster manager node. Default is 30s . |
timeout | Time | How long to wait for the response to return. Default is 30s . |
write_index_only | Boolean | Whether OpenSearch should apply mapping updates only to the write index. |
Sample Request
The following request creates a new mapping for the sample-index
index:
PUT /sample-index/_mapping
{
"properties": {
"age": {
"type": "integer"
},
"occupation":{
"type": "text"
}
}
}
Sample Response
Upon success, the response returns "acknowledged": true
.
{
"acknowledged": true
}
