Version 2.1.0

Release date: 2015-11-12

Updates:

• Asynchronous network transmission and performance tuning: The queries per second (QPS) performance is increased by several times when CPU utilization remains unchanged.

• Flexible and simple asynchronous operations: Callbacks can be imported, and future can be returned at the same time.

• Content related to OSS SDK is removed: The new version of Tablestore SDK for Java contains code that is related only to Tablestore SDK. The directory structure is fine-tuned.

• Retry logic optimization: The default retry logic is optimized. Retry attempts are supported for single-row errors that occur when batch operations are performed. A simpler method is provided to help you modify the retry logic.

• Log optimization: Detailed logs are recorded for the time period from when a request is sent to when the request is received. Log records of slow requests are provided. Trace IDs can be used to view the comprehensive log records for the requests that are sent between Tablestore SDK for Java and the backend service.

• OTSWriter that can be used to import a large amount of data at a time: provides a simple and efficient data import experience.

• Other improvements: Tool functions that support multiple data types are provided. The operation that can be called to calculate data sizes is provided.

Note:

The following compatibility issues exist between Tablestore SDK for Java V2.1.0 and V2.0.4:

• The import path for specific classes must be modified after a later version of Tablestore SDK for Java is used. Packages of specific 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 both SDKs must be included in the packages of Tablestore.

• If you no longer use an OTSClient instance, 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.

• The names of specific configuration items in ClientConfiguration are changed. For example, time units are added to the names.

• Modifications are made to dependencies of Tablestore SDK for Java V2.1.0. For example, HttpAsyncClient and Joda-Time are used. If errors occur when you run the program, check whether the imported dependencies are the same as the existing dependencies.
