Bulk updates not respecting _version

Anand_Nalya · October 28, 2013, 5:35am

Hi,

I'm trying to do bulk updates on a index with _version in the conditional
but ES is updating the document even when there is a version conflict:

{"update":{"_index":"urls","_type":"url","_version":1,"_id":"ef2ec2fada4c476c0a7d744236ad9551"}}
{"doc":{"p1":"abc"}}
{"update":{"_index":"urls","_type":"url","_version":1,"_id":"5e343487dc6c0ad2b264ffbaffd946c9"}}
{"doc":{"p2":"xyz"}}

_version is work properly when I update the documents individually.

Regards,
Anand

Hello,
I need the same functionality.
Also is there a way to access _version field in script?

Thanks

Bulk update logic
@ https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/action/bulk/BulkRequest.java#L356
is similar to that of delete wrt. version, but still its not working.

This is strange.

You apparently use random _id's, so can you please show more information
about how you create a version conflict?

Following is another test:

GET http://localhost:9200/test/type1/1

{
```
"_index": "test",
```
```
"_type": "type1",
```
```
"_id": "1",
```
```
"_version": 4,
```
```
"exists": true,
```
```
"_source":
```
```
{
```
```
    "field1": "value1"
```
```
}
```
}

POST: http://localhost:9200/_bulk
{ "update" : { "_index" : "test", "_type" : "type1", "_id" :
"1","_version":1 } }
{"doc":{ "field1" : "value1" }}

returns

{
```
"took": 60,
```
```
"items":
```
```
[
```
```
    {
```
```
        "update":
```
```
        {
```
```
            "_index": "test",
```
```
            "_type": "type1",
```
```
            "_id": "1",
```
```
            "_version": 5,
```
```
            "ok": true
```
```
        }
```
```
    }
```
```
]
```
}

Bulk update ignore doc versioning, because update merges old and new
versions.

Support for the version parameter on update / bulk update is only available
in master:

github.com/elastic/elasticsearch

Update api doesn't support versioning

closed 11:47AM - 20 Jun 13 UTC

bleskes

>bug v1.0.0.Beta1

To reproduce ``` sh curl -XPOST http://localhost:9200/test/test/1 -d'{ "fie…ld": "value1" }' ``` The internal version is now 1. Now index again: ``` sh curl -XPOST http://localhost:9200/test/test/1 -d'{ "field": "value2" }' ``` Internal version is now 2. Try to update using version=1 (should fail) ``` sh curl -XPOST "http://localhost:9200/test/test/1/_update?version=1" -d'{ "doc": { "field": "value3" } }' ``` Which doesn't fail with a version conflict but returns: ``` json {"ok":true,"_index":"test","_type":"test","_id":"1","_version":3,"_previous_version":2} ``` PS. The java api's UpdateRequestBuilder doesn't have a setVersion method

Very interesting. I had synthesized my own update by a combination of
get-by-id, my own additions/deletions to the existing _source, and then an
"index" action with the updated _source along with versioning.

One question about ElasticSearch's "update" action (added since 0.90.1):
Does this actually update the _source?
