重要变更介绍
性能优化
新版本探索了更多性能优化的方向和非常规的一些优化手段。
-
长连接池: 100 并发 qps 提升 4%, p99 降低 18%
-
多路复用: 100 并发 qps 提升 7%, p99 降低 24%
-
gRPC: 100 并发 qps优化 8%，p99优化 10%
代码产物精简优化
-
移除非序列化代码（默认） ：原 kitex_gen Thrift 产物代码为保持与 Apache 的一致性，会生成 Processor 代码，但 Kitex 并不需要这些代码。为解决大家的产物痛点问题，此版本默认去除这部分代码，生成速度提升约 10%。
-
移除 Apache Codec 代码（配置移除） ：Kitex 有自定义的 FastCodec 代码，旧版本仅在 Buffered 包需要使用 Apache Codec。Kitex 新版本实现 SkipDecoder，在开启后就可以完全不依赖 Apache Codec，进而移除代码，产物体积可减少约 50%。使用方式见 SkipDecoder。
SkipDecoder:

新特性
Thrift 按需序列化 ：支持定义 FieldMask 实现数据按需序列化（字段裁剪、合并，RPC性能优化等），详见 Thrift FieldMask RFC。
Thrift FieldMask RFC:
https://github.com/cloudwego/thriftgo/tree/main/fieldmask
功能优化
-
熔断 ：支持自定义熔断的错误类型
-
异常重试 ：代码配置的自定义结果重试增加 ctx 参数，方便用户结合 ctx 信息判断是否重试
-
移除一致性哈希中的缓存 ：解决hash key分散导致的延迟变高、内存上涨的问题。移除缓存后，面对 Key 特别分散甚至接近随机分布的场景，可以有效降低内存占用与管理缓存的消耗。
用户体验优化
Kitex 工具兼容性检测 ：优化过去产物引入新定义导致的 undefined 编译问题。Kitex 工具在生成代码前会检查 go.mod 中使用的 Kitex 版本。若 Kitex 工具和 Kitex 版本不兼容，则不会生成代码并给出相应的升降级提示。
