I created a new entity connected to Hibernate Elastic Search and indexed it. Upon retrieving the indexed data, I noticed that updating the entity using the student ID resulted in deleting the existing data and re-inserting the updated data. To preserve the existing data along with the updated data, I need to merge the updated data with the existing data before indexing the entity.
Student insertion request
```auto
{
"studentId": "1",
"studentMark": "10",
"studentName": "LMN",
"data": [
{
"id": "1",
"mark": "10",
"name": "ABC",
"status": "Inprogress"
},
{
"id": "5",
"mark": "10",
"name": "XYZ",
"status": "READY_TO_PROCESS"
}
]
}
```
Upon completing the data insertion, I fetched the latest data from the Elasticsearch server.
**Response**
```auto
{
"took": 8,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 1.0,
"hits": [
{
"_index": "student-000001",
"_type": "_doc",
"_id": "1",
"_score": 1.0,
"_source": {
"data": [
{
"id": "1",
"mark": "10",
"name": "ABC",
"status": "Inprogress"
},
{
"id": "5",
"mark": "10",
"name": "XYZ",
"status": "READY_TO_PROCESS"
}
],
"studentId": "1",
"studentMark": "10",
"studentName": "LMN",
"_entity_type": "StudentEntity"
}
}
]
}
}
```
Update the entity using the student ID.
**Request**
```auto
{
"studentId": "1",
"studentMark": "10",
"studentName": "OPQ",
"data": [
{
"id": "1",
"mark": "10",
"name": "HIJ",
"status": "READY_TO_PROCESS"
}
]
}
```
After updating the data, I retrieved it again from the Elasticsearch server to verify the changes.
**Response**
```auto
{
"took": 8,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 1.0,
"hits": [
{
"_index": "student-000001",
"_type": "_doc",
"_id": "1",
"_score": 1.0,
"_source": {
"data": [
{
"id": "1",
"mark": "10",
"name": "HIJ",
"status": "READY_TO_PROCESS"
}
],
"studentId": "1",
"studentMark": "10",
"studentName": "OPQ",
"_entity_type": "StudentEntity"
}
}
]
}
}
```
i found that after updating the entity defiantly its deleting the existing data and re-inserting the new changes.
How to avoid this change. i need to get existing as well as the updated data. Please help me too fix this issue
