Changelog

[0.48.0-public] - 2024-04-22

Added

• Introduced odps-sdk-udf module to allow batch data reading in UDFs for MaxCompute, significantly improving performance in high-volume data scenarios.
• Table now supports retrieving ColumnMaskInfo, aiding in data desensitization scenarios and relevant information acquisition.
• Support for setting proxies through the use of odps.getRestClient().setProxy(Proxy) method.
• Implementation of iterable RecordReader and RecordReader.stream() method, enabling conversion to a Stream of Record objects.
• Added new parameters upsertConcurrentNum and upsertNetworkNum in TableAPI RestOptions for more detailed control for users performing upsert operations via the TableAPI.
• Support for Builder pattern in constructing TableSchema.
• Support for toString method in ArrayRecord.

Improved

• UploadSession now supports configuration of the GET_BLOCK_ID parameter to speed up session creation when the client does not need blockId.
• Enhanced table creation method using the builder pattern (TableCreator), making table creation simpler.

Fixed

• Fixed a bug in Upsert Session where the timeout setting was configured incorrectly.
• Fixed the issue where TimestampWritable computed one second less when nanoseconds were negative.

更新日志

[0.48.0-public] - 2024-04-22

新增

• 引入了odps-sdk-udf模块，支持在UDF中按批读取MaxCompute数据，能在大数据量场景下显著提高性能。
• Table现支持获取ColumnMaskInfo，用于数据脱敏场景，方便相关信息的获取。
• 新增通过odps.getRestClient().setProxy(Proxy)方法设置代理的支持。
• 实现了可迭代的RecordReader以及RecordReader.stream()方法，允许将其转换为Record对象的流。
• 在TableAPI RestOptions中新增upsertConcurrentNum和upsertNetworkNum参数，为使用TableAPI进行upsert操作的用户提供更细致的控制。
• 支持使用Builder模式来构建TableSchema。
• ArrayRecord支持toString方法。

变更

• 现在，当用户使用StsAccount但不传递StsToken时，将被视作使用AliyunAccount。

改进

• UploadSession现支持配置GET_BLOCK_ID参数，当客户端不需要blockId时，可以加速创建Session的速度。
• 使用builder模式(TableCreator)加强了表的创建方法，现在可以更简单地创建表了。

修复

• 修复了Upsert Session获取连接时，超时时间配置错误的问题。
• 修复了TimestampWritable在纳秒为负数时计算出错一秒的问题。
