elasticsearchHow can I use elasticsearch to manage transactions?

Elasticsearch can be used to manage transactions with the help of the _bulk API. This API allows you to send multiple documents in a single request. The documents can be of any type, including transactions.

For example, the following code block can be used to create two transactions in a single request:

curl -X POST "localhost:9200/_bulk?pretty" -H 'Content-Type: application/json' -d'
{ "index": { "_id": 1 } }
{ "transaction_type": "credit", "amount": 500 }
{ "index": { "_id": 2 } }
{ "transaction_type": "debit", "amount": 100 }
'

The output of the above code would be:

{
  "took" : 4,
  "errors" : false,
  "items" : [
    {
      "index" : {
        "_index" : "_bulk",
        "_type" : "_doc",
        "_id" : "1",
        "_version" : 1,
        "result" : "created",
        "_shards" : {
          "total" : 2,
          "successful" : 1,
          "failed" : 0
        },
        "status" : 201
      }
    },
    {
      "index" : {
        "_index" : "_bulk",
        "_type" : "_doc",
        "_id" : "2",
        "_version" : 1,
        "result" : "created",
        "_shards" : {
          "total" : 2,
          "successful" : 1,
          "failed" : 0
        },
        "status" : 201
      }
    }
  ]
}

The code consists of the following parts:

1. curl -X POST "localhost:9200/_bulk?pretty" -H 'Content-Type: application/json' -d': This is the command used to send a request to the Elasticsearch server.

2. { "index": { "_id": 1 } }: This is the first document that will be indexed. It contains an index property with an _id property set to 1.

3. { "transaction_type": "credit", "amount": 500 }: This is the second document that will be indexed. It contains a transaction_type property set to credit and an amount property set to 500.

4. { "index": { "_id": 2 } }: This is the third document that will be indexed. It contains an index property with an _id property set to 2.

5. { "transaction_type": "debit", "amount": 100 }: This is the fourth document that will be indexed. It contains a transaction_type property set to debit and an amount property set to 100.

6. ': This is the end of the request.

This code will create two transactions in a single request, which can be used to manage transactions with Elasticsearch.
