I'm using the Java SDK to update a document, like so:
```auto
UpdateResponse response = elasticsearchService.getClient().update(u -> u.index(INDEX)
.id(id)
.doc(JsonData.of(myObject)).refresh(Refresh.True), Void.class);
```
In this case myObject has a `@Transient` property on it: `id`, which I populate with `_id` when I load it from elasticsearch.
Unfortunately, when I update like this, the `@Transient` `id` field gets serialised and written into elasticsearch.
How can I prevent that?

`@Transient` is a JPA annotation that has no impact on JSON serialization. You should probably add `@JsonIgnore` on that property.

Thanks, but that's not going to work in this situation. I actually want the id property to be serialised for my user interface.
Literally the only time I don't want it serialised is when it's being written into elasticsearch.
Are there other options? Perhaps something using a Jackson Mixin?

You should look at Jackson's views and configure a view on the `ObjectMapper` used to create the `JacksonJsonpMapper` in your Elasticsearch client.
See [https://www.baeldung.com/jackson-json-view-annotation](https://www.baeldung.com/jackson-json-view-annotation)

This looks good - do you have an example for how one might configure the ObjectMapper using the Java SDK?
```java
this.restClient = RestClient.builder(new HttpHost(elasticsearchHost, elasticsearchPort, elasticsearchScheme))
.setHttpClientConfigCallback(createHttpClientConfigCallback(elasticsearchUsername, elasticsearchPassword, Boolean.TRUE.equals(allowSelfSignedCert)))
.setRequestConfigCallback(createRequestConfigCallback())
.build();
this.client = new ElasticsearchClient(new RestClientTransport(restClient, new JacksonJsonpMapper()));
```
Assuming where I'm using that `new JacksonJsonpMapper()`...?

Yes. There is an [additional constructor](https://artifacts.elastic.co/javadoc/co/elastic/clients/elasticsearch-java/8.12.2/co/elastic/clients/json/jackson/JacksonJsonpMapper.html#%3Cinit%3E(com.fasterxml.jackson.databind.ObjectMapper)) where you can provide a Jackson `ObjectMapper`, which you can configure at will.
