New features

• The A/B test feature is supported.

• The collection of behavioral data is supported.

• Maven dependency

<dependency>
  <groupId>com.aliyun.opensearch</groupId>
  <artifactId>aliyun-sdk-opensearch</artifactId>

</dependency>

• The drop-down suggestion feature is supported.

New features

• Scroll queries support sorting based on a single field of the int type.

• The switchTo method is added to the AppClient class to switch the versions of multiple applications at a time.

• Cross-application queries are supported.

• You can use an application name or ID to query or update the quotas of the application.

• You can modify billing models and quotas for applications, such as specifications, storage capacity, and computing resources.

• The drop-down suggestion feature is updated.

Fixed bug

• After a response is received for a request, the request is closed. If the request is not closed and the response is in the GZIP format, the connection used by the request is still occupied instead of being returned to the connection pool. In this case, the connections in the connection pool will run out, which will cause the SDK to stop responding.

• Maven dependency

<dependency>
  <groupId>com.aliyun.opensearch</groupId>
  <artifactId>aliyun-sdk-opensearch</artifactId>
  <version>3.1.3</version>
</dependency>

• Third-party dependencies are added to OpenSearch packages. To reduce dependency conflicts, all dependencies except slf4j-api are relocated in the OpenSearch packages.

• The data format FULLJSON is supported.

• The documents in the buffer are cleared regardless of whether a commit succeeds or fails. This reduces the ambiguity when you use the OpenSearch SDK or API.

• The confirmation component for the drop-down suggestion feature is released and the SDK is available.
