I have APIs[application] which update documents partially as per the action on the client side.

Now the issue that I am facing is

> ```
> "type": "version_conflict_engine_exception",
> "reason": "[5dede8546cce890029d8dfa6]: version conflict, required seqNo [1008824], primary term [1]. current document has seqNo [1068598] and primary term [1]",
> 
> ```

The issue is straight forward that doc is getting modified concurrently.

Will the **retry\_on\_conflict** option for the update api maintain the sanity that the documents are updated properly without information loss ??

Is this option available at the elastic client level ?

any other recommendations are welcome .

Thanks a lot
