REPLACE works similarly to INSERT, but it marks the previous document with the same ID as deleted before inserting a new one.

For HTTP JSON protocol, two request formats are available: Manticore and Elasticsearch-like. You can find both examples in the provided examples.

SQL:

REPLACE INTO products VALUES(1, "document one", 10);

Query OK, 1 row affected (0.00 sec)

JSON

POST /replace
-H "Content-Type: application/x-ndjson" -d '
{
  "index":"products",
  "id":1,
  "doc":
  {
    "title":"product one",
    "price":10
  }
}
'

{
  "_index":"products",
  "_id":1,
  "created":false,
  "result":"updated",
  "status":200
}

Elasticsearch

PUT /products/_doc/2
{
  "title": "product two",
  "price": 20
}

POST /products/_doc/
{
  "title": "product three",
  "price": 10
}

{
"_id":2,
"_index":"products",
"_primary_term":1,
"_seq_no":0,
"_shards":{
    "failed":0,
    "successful":1,
    "total":1
},
"_type":"_doc",
"_version":1,
"result":"created"
}

{
"_id":2235747273424240642,
"_index":"products",
"_primary_term":1,
"_seq_no":0,
"_shards":{
    "failed":0,
    "successful":1,
    "total":1
},
"_type":"_doc",
"_version":1,
"result":"created"
}

PHP:

$index->replaceDocument([
   'title' => 'document one',
    'price' => 10
],1);

Array(
    [_index] => products
    [_id] => 1
    [created] => false
    [result] => updated
    [status] => 200
)

Python:

indexApi.replace({"index" : "products", "id" : 1, "doc" : {"title" : "document one","price":10}})

{'created': False,
 'found': None,
 'id': 1,
 'index': 'products',
 'result': 'updated'}

javascript:

res = await indexApi.replace({"index" : "products", "id" : 1, "doc" : {"title" : "document one","price":10}});

{"_index":"products","_id":1,"result":"updated"}

java:

docRequest = new InsertDocumentRequest();
HashMap<String,Object> doc = new HashMap<String,Object>(){{
            put("title","document one");
            put("price",10);
}};
docRequest.index("products").id(1L).setDoc(doc);
sqlresult = indexApi.replace(docRequest);

class SuccessResponse {
    index: products
    id: 1
    created: false
    result: updated
    found: null
}

When you run a REPLACE, the previous document is not removed, but it’s marked as deleted, so the table size grows until chunk merging happens, and the marked documents won’t be included. To force a chunk merge, use the OPTIMIZE statement.

REPLACE INTO table [(column1, column2, ...)]
    VALUES (value1, value2, ...)
    [, (...)]

To use the HTTP JSON interface with REPLACE, use the /replace endpoint. There’s also a synonym endpoint, /index.

You can replace multiple documents at once. Check bulk adding documents for more information.

HTTP:

REPLACE INTO products(id,title,tag) VALUES (1, 'doc one', 10), (2,' doc two', 20);

Query OK, 2 rows affected (0.00 sec)
