- Asynchronous network transmission and performance tuning: Queries per second (QPS) is increased by several times when CPU utilization remains unchanged.
- Flexible and easy-to-use asynchronous operations: callback can be imported, and future can be returned simultaneously.
- Content related to OSS SDK removed: The version of Tablestore SDK for Java includes code related only to Tablestore SDK. The directory structure is fine-tuned.
- Retry logic optimization: The default retry logic is optimized. Retry attempts are allowed for single-row errors that occur when batch operations are performed. A clearer method is provided to customize retry logic.
- Log optimization: Detailed logs from when requests are sent to when requests are received are recorded. Log records of slow requests are provided. Trace IDs can be used to view the comprehensive log records of the communications between Tablestore SDK for Java and the backend service.
- The OTSWriter plug-in supported to import multiple data: delivers easy-to-use and efficient data import experience.
- Other improvements: Tools and functions that support a variety of data types are provided. The operation used to calculate data sizes is provided.
The following incompatibilities exist between Tablestore SDK for Java V2.1.0 and V2.0.4:
- The import path for several classes must be modified after the later version of Tablestore SDK for Java is used. Packages of several classes are modified. For example, the package of ClientConfiguration is changed from com.aliyun.openservices to com.aliyun.openservices.ots. These packages are modified because Tablestore SDK is separated from OSS SDK. The classes shared by the both SDKs must also be in the packages of Tablestore.
- If you no longer use an OTSClient instance in some scenarios, for example, before the program exits, you must call the shutdown method of OTSClient to release all threads and connection resources of the OTSClient instance.
- Names of some configuration items of ClientConfiguration are adjusted. For example, time units are added to the names.
- Adjustments are made to dependencies of later versions of Tablestore SDK for Java. For example, HttpAsyncClient and Joda-Time are used. If you encounter problems when you run the program, check whether imported dependencies conflict with the existing dependencies.
