描述

Proposed logic:

1.  Add flag where appropriate for supports dictionary replacement if there is a possibility it can be used.

2.  Only add compressed buffers when requested.

 

Reading should validate enums are in range AND implementation supports them.

调研方向

从链接的迁移文档和 Java 子任务开始,以确定 Java 特有的范围。检查当前如何处理 feature 值,然后验证 Java 实现是否使用 feature 枚举、验证其范围和支持情况,并且仅在请求时添加压缩缓冲区。
