How to use the Bulk API with cURL In Databases
Step 1: Preparing Bulk Data
Prepare your bulk data in the NDJSON format. Save the following data to a file named bulk_data.json:
{ "index": { "_index": "myindex", "_id": "1" } }
{ "name": "John Doe", "age": 30, "city": "New York" }
{ "index": { "_index": "myindex", "_id": "2" } }
{ "name": "Jane Smith", "age": 25, "city": "San Francisco" }
{ "index": { "_index": "myindex", "_id": "3" } }
{ "name": "Sam Brown", "age": 35, "city": "Chicago" }
Step 2: Sending the Bulk Request
Use cURL to send the bulk request to Elasticsearch. Run the following command in your terminal:
curl -H "Content-Type: application/x-ndjson" -XPOST "http://localhost:9200/_bulk" --data-binary "@bulk_data.json"
Output:
You should see a response indicating the success or failure of each operation:
{
"took": 30,
"errors": false,
"items": [
{
"index": {
"_index": "myindex",
"_id": "1",
"result": "created",
"status": 201
}
},
{
"index": {
"_index": "myindex",
"_id": "2",
"result": "created",
"status": 201
}
},
{
"index": {
"_index": "myindex",
"_id": "3",
"result": "created",
"status": 201
}
}
]
}
