I currently use ElasticSearch in Spring Boot. The ES version is 6.2.2 and an error occurs because an option such as ignore_throttle does not exist. When I check the library version, it is judged that the high level client 7.x version is the problem, but if I change the version to 6.2.2, an unknown error occurs and I just try to use it. Could you possibly delete the parameter?
implementation 'org.springframework.boot:spring-boot-starter-data-elasticsearch:2.1.10.RELEASE'
request
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(QueryBuilders.matchAllQuery());
searchRequest.source(sourceBuilder);
Is the version of spring boot you are using > 2.1.5

Currently we are on spring-data-elasticsearch 3.2.6 + elasticsearch 6.8.
We are moving to new elasticsearch 7.x. Do I have to update spring-data-elasticsearch to 4.x? We only use ElasticsearchRepository in spring-data-elasticsearch. And we don't need to use any new feature in elasticsearch 7.x.
If we are moving to elasticsearch 8.x in the future, do I need update spring-data-elasticsearch ?
Update:
What Elasticsearch client does Spring-Data-Elasticsearch use under the hood?
All methods in the `ElasticsearchRepository` are deprecated. What should do I use?
I found some discussions in above threads. Here is my summary.
Operations with Templates:
ElasticsearchTemplate implements ElasticSearchOperation. It uses TransportClient(which is deprecated in ES 7 and has been removed in ES8)
ElasticsearchRestTemplate implements ElasticSearchOperation. It uses high level client(which is deprecated in ES 7.16.0. It will be removed in future. #Deprecated(since = "7.16.0", forRemoval = true) )
ReactiveElasticsearchTemplate implements ReactiveElasticsearchOperations. It uses Reactive Client.
Repository
ElasticsearchRepository uses TransportClient as default. All methods in the ElasticsearchRepository are deprecated now.
Reactive Elasticsearch repository builds on ReactiveElasticsearchOperations.
Due to underlying TransportClient or HigLevelRestClient has been deprecated, can I conclude that the correct way is to use Reactive Client(ReactiveElasticsearchTemplate or Reactive Elasticsearch repository) ?
The new Elasticsearch would be 8.
Val already put the link to the compatibility matrix in his comment.
Version 3.2.6 is pretty outdated (March 25 2020) and out of support since October 2020.
The first thing you can try is to see if your application works with a 7 cluster - although I doubt that, I can't tell you exactly what had changed in the API, but there was quite some stuff.
What you should not do is putting newer Elasticsearch libraries on the classpath than the ones that Spring Data Elasticsearch was built with, this will in most cases make problems.
But I'd recommend to upgrade your application anyway and keep it regularly up to date.
As for future upgrade to version 8: It is possible to send a compatibility header in your requests (this can be done in Spring Data Elasticsearch 4) and the Elasticsearch cluster should respond in a format that is compatible with a client expecting version 7. I wrote should, because it does not conform to this in every case - I reported one case that is fixed now. But I wouldn't rely on that.
Again, please update your application and keep it up to date, not only because of Spring Data Elasticsearch, but also because these updates always include bug and/or security fixes.
We have a java application (spring boot + hibernate search + elastic search).
Application is working fine on elastic search version 6.8
Recently, we have created a new cluster in aws with version 7.10.2 and updated elastic search endpoint in my java application.
After updating the elastic search endpoint I am getting error Can't update put mapping Types cannot be provided in put mapping requests, unless the include_type_name parameter is set to true and due to this unable to start the server.
I am not sure where to set include_type_name=true because all the indexes gets created automatically with #Indexed.
Can someone please let us know how can we fix this issue ?
Thanks #yrodiere for your response.
I tried to upgrade below dependencies version but unfortunately not able to fix it.
Previous Version:
compile 'org.hibernate:hibernate-search-orm:5.9.3.Final'
compile 'org.hibernate:hibernate-search-elasticsearch:5.9.3.Final'
compile 'org.hibernate:hibernate-search-elasticsearch-aws:5.9.3.Final'
Updated version :
compile 'org.hibernate:hibernate-search-orm:5.9.3.Final
compile 'org.hibernate.search:hibernate-search-backend-elasticsearch:6.1.1.Final'
compile 'org.hibernate.search:hibernate-search-backend-elasticsearch-aws:6.1.1.Final'
Note: If I downgrade this org.hibernate:hibernate-search-orm:5.9.3.Final then getting CE
am i missing something?
You're probably using Hibernate Search 5.x. In Hibernate Search 5.x, the Elasticsearch integration was experimental and only compatible with Elasticsearch up to version 5.6.
The fact that your application was working fine with Elasticsearch 6.8 was pure luck: Hibernate Search 5.x was never intended to work with Elasticsearch 6+.
To upgrade to a more recent version of Elasticsearch, you must upgrade to Hibernate Search 6.0 (or later). The API is different, but there is a very detailed migration guide, and at least you will get production-ready (non-experimental) Elasticsearch integration (plus tons of improvements).
Note that Hibernate Search 6.x also requires upgrading to Hibernate ORM 5.4; see this compatibility matrix.
Can anyone help me to undersand:
In Spring Data Couchbase: spring-data-couchbase : 4.3.0
Couchbase Version: 6.6.2
By using couchbasetemplate
findById(Entity.class).one(id) is working fine, I am able to fetch
data
findByQuery(Entity.class).all() returning empty array
findByQuery(Entity.class).count() returning 0
This is described in https://github.com/spring-projects/spring-data-couchbase/issues/1321 which is fixed in today's release of 4.3.2.
If the problem persists, please open a new issue https://github.com/spring-projects/spring-data-couchbase/issues/new
spring data elasticsearch uses 7.x client version and my production elasticsearch version is 6.4.2. So I changed the version and got the following exception. How to safely change version in spring data es?

An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.data.elasticsearch.core.ReactiveElasticsearchTemplate.<init>(ReactiveElasticsearchTemplate.java:108)
The following method did not exist:
org.elasticsearch.action.support.IndicesOptions.strictExpandOpenAndForbidClosedIgnoreThrottled()Lorg/elasticsearch/action/support/IndicesOptions;
The method's class, org.elasticsearch.action.support.IndicesOptions, is available from the following locations:

Action:
Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.action.support.IndicesOptions
You can’t use a Elasticsearch 6 cluster with Spring Data Elasticsearch 4 which uses Elasticsearch 7 libraries. The Elasticsearch REST API that is used had breaking changes between version 6 and 7.
You can try to use Spring Data Elasticsearch 3.2.x which targets 6.8; I currently don’t know if there were breaking changes between Elasticsearch 6.4 and 6.8, you’ll have to try it.
I am using Elasticsearch version 2.3.1
I want to implement Deletebyquery of ES in java
Es have docs for that https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html
This doc stats that In deletebyquery request we can have a params like wait_for_completion=false , wait_for_active_shards , etc
This is fine for curl request, But my problem is I want to implement the same using java api, with that wait_for_completion flag set.
My java code for Deletebyquery in java
DeleteByQueryRequestBuilder deleteRequest = DeleteByQueryRequestBuilder(esType, DeleteByQueryAction.INSTANCE)
.setIndices(index)
.setTypes(type);
deleteRequest.setQuery(boolQuery);
DeleteByQueryResponse resp = deleteRequest.get();
I want to know where I can add wait_for_completion flag in java api request, kindly advice me. Thanks
The document link provided in the OP is for the latest version of elasticsearch.
Elasticsearch 2.3 supports DeleteByQuery only via a plugin.
The external plugin does not have wait_for_completion option.
The feature was re-introduced in 5.x.
