Uber 如何扩展数据复制能力以实现每天 PB 级数据迁移
Uber 重视可靠的数据湖（Data Lake），其分布在本地和云环境中。这种多区域架构在有限的网络带宽下为确保可靠且及时的数据访问带来了挑战，尤其是在灾难恢复场景中需要实现无缝的数据可用性。Uber 使用 Hive Sync 服务，该服务基于 Apache Hadoop® Distcp（Distributed Copy）进行数据复制。然而，随着 Uber 数据湖规模超过 350 PB，Distcp 的局限性逐渐显现。本文探讨了针对 Distcp 所做的优化，以提升其性能并满足 Uber 在分布式基础设施上日益增长的数据复制和灾难恢复需求。

Go 1.26 黑科技：跳过 GC 直接释放内存，性能飙升 200%
最近，Go 语言社区围绕一个全新的内存管理提案展开了激烈讨论：在不依赖垃圾回收 (GC) 的情况下直接释放并重用内存。#74299 引入了 runtime.free 及相关机制，试图让编译器和标准库在特定场景下安全地跳过 GC，对短命的内存对象进行即时回收利用github.comgo.googlesource.com。此举被认为可能为 Go 带来一次性能上的革命：初步原型显示，在 strings.Builder 这样的场景中，利用该机制性能提升可达 2 倍github.com。本文将回顾 Go 内存管理领域从 arena 实验到 memory region 构想，再到 runtime.free 提案的探索之旅，并剖析这一新提案的技术细节、产生的意义、演化过程，以及对普通开发者的影响。 runtime.free 将在 Golang1.26
