Changelog

[0.48.6-public] - 2024-07-17

Added

• Serializable Support:
  • Key data types like ArrayRecord, Column, TableSchema, and TypeInfo now support serialization and deserialization, enabling caching and inter-process communication.
• Predicate Pushdown:
  • Introduced Attribute type predicates to specify column names.

Changed

• Tunnel Interface Refactoring:
  • Refactored Tunnel-related interfaces to include seamless retry logic, greatly enhancing stability and robustness.
  • Removed TunnelRetryStrategy and ConfigurationImpl classes, which are now replaced by TunnelRetryHandler and Configuration respectively.

Improve

• SQLExecutor Optimization:
  • Improved performance when executing offline SQL jobs through the SQLExecutor interface, reducing one network request per job to fetch results, thereby decreasing end-to-end latency.

Fixed

• Decimal Read in Table.read:
  • Fixed issue where trailing zeroes in the decimal type were not as expected in the Table.read interface.

更新日志

[0.48.6-public] - 2024-07-17

新增

• 支持序列化：
  • 主要数据类型如 ArrayRecord、Column、TableSchema 和 TypeInfo 现在支持序列化和反序列化，能够进行缓存和进程间通信。
• 谓词下推：
  • 新增 Attribute 类型的谓词，用于指定列名。

变更

• Tunnel 接口重构：
  • 重构了 Tunnel 相关接口，加入了无感知的重试逻辑，大大增强了稳定性和鲁棒性。
  • 删除了 TunnelRetryStrategy 和 ConfigurationImpl 类，分别被 TunnelRetryHandler 和 Configuration 所取代。

优化

• SQLExecutor 优化：
  • 在使用 SQLExecutor 接口执行离线 SQL 作业时进行优化，减少每个作业获取结果时的一次网络请求，从而减少端到端延时。

修复

• Table.read Decimal 读取：
  • 修复了 Table.read 接口在读取 decimal 类型时，后面补零不符合预期的问题。
