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 REST (low-level) client
Core low-level client which lets you interact with OpenSearch clusters through HTTP methods and JSON, it is also used by the two other higher level clients for connecting to the cluster.
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.
OpenSearch Java client
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.
Installation
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>1.3.0</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>1.3.0</version>
</dependency>OpenSearch Java client
The java 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-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>1.3.0</version>
</dependency>Extension Configuration Reference
Configuration property fixed at build time - All other configuration properties are overridable at runtime

The list of hosts of the OpenSearch servers. Environment variable: |
list of host:port |

The protocol to use when contacting OpenSearch servers. Set to "https" to enable SSL/TLS. Environment variable: |
string |
|
The username for basic HTTP authentication. Environment variable: |

|
The maximum number of connections to all the OpenSearch servers. Environment variable: |
int |
|
The maximum number of connections per OpenSearch server. Environment variable: |
int |
|
The number of IO thread. By default, this is the number of locally detected processors. Thread counts higher than the number of processors should not be necessary because the I/O threads rely on non-blocking operations, but you may want to use a thread count lower than the number of processors.
