Maven dependency

    <artifactId>aliyun-sdk-opensearch</artifactId>
    <version>3.3.0</version>
</dependency>

Fixed

Fixed a connection pool exhaustion issue. When a response arrived in GZIP format and the request was not explicitly closed, the connection remained occupied instead of returning to the pool. This caused the pool to run out of connections and the SDK to stop responding. Requests are now closed after the response is received.

V3.1.3 (2017-04-14)

Maven dependency

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

Added

Added support for the FULLJSON format.

Changed

Relocated all third-party dependencies into the OpenSearch package to reduce conflicts with official dependencies. The slf4j-api component is excluded from relocation.
The commit method now removes documents from the SDK client buffer regardless of whether the call succeeds. This reduces ambiguity when using the SDK or calling API operations.
