Quarkus Opensearch Extension
The quarkus-opensearch extension allows you to connect to an OpenSearch cluster using the clients provided by the OpenSearch project.
OpenSearch Clients
OpenSearch provides three different flavours of clients for connecting to the cluster. This extension has support for all three of them.
OpenSearch Java Client
This is the latest implementation of the OpenSearch clients, when starting a new project you should use this client and not bother about the others.
This will be the only OpenSearch Client supported in the future.
Just like the OpenSearch REST high-level level, the OpenSearch Java client lets you interact with OpenSearch through Java methods and data structures. In comparison to the REST high-level, it has no dependency to org.opensearch:opensearch and also provides an async client implementation.
|
Deprecation
The OpenSearch REST clients are deprecated. Support will be removed in OpenSearch version 3.0.0. It is recommended to switch to the Java client. We will try to support the REST clients as long as possible, but if you start a new project this is not the client you should use anymore. |
OpenSearch REST High-Level Client
The OpenSearch Java high-level REST client lets you interact with your OpenSearch clusters and indices through Java methods and data structures rather than HTTP methods and JSON.
Installation
OpenSearch Java client
The java client does not have any dependencies on the REST client. All clients are sharing most of the configuration properties.
The AWS related configuration properties quarkus.opensearch.aws.* are only applicable to this java client.
If you want to use this client all you need to do is add the io.quarkiverse.opensearch:quarkus-opensearch-java-client extension first to your build file.
with Maven, add the following dependency to your POM file:
<dependency>
<groupId>io.quarkiverse.opensearch</groupId>
<artifactId>quarkus-opensearch-java-client</artifactId>
<version>1.13.0</version>
</dependency>OpenSearch REST High-Level Client
The REST High-Level Client depends on the REST client and does not require any additional configuration.
If you want to use this client all you need to do is add the io.quarkiverse.opensearch:quarkus-opensearch-rest-high-level-client extension first to your build file.
with Maven, add the following dependency to your POM file:
<dependency>
<groupId>io.quarkiverse.opensearch</groupId>
<artifactId>quarkus-opensearch-rest-high-level-client</artifactId>
<version>1.13.0</version>
</dependency>OpenSearch REST Low-Level Client
If you want to use this extension, you need to add the io.quarkiverse.opensearch:quarkus-opensearch-rest-client extension first to your build file.
For instance, with Maven, add the following dependency to your POM file:
<dependency>
<groupId>io.quarkiverse.opensearch</groupId>
<artifactId>quarkus-opensearch-rest-client</artifactId>
<version>1.13.0</version>
</dependency>Extension Configuration Reference
Configuration property fixed at build time - All other configuration properties are overridable at runtime
