1. 什么是 Fluent Bit ？

Fluent Bit 是 CNCF 在 Fluentd 旗下的一个子项目。

Fluent Bit 是一个开源、多平台的日志处理工具，旨在成为处理和分发日志的通用瑞士刀。

如今，我们环境中信息来源的数量正在不断增加。处理大规模的数据收集是复杂的，收集和聚合不同的数据需要一个专门的工具，可以处理：

不同的信息来源。
不同的数据格式。
数据可靠性。
安全性。
灵活的路由。
多目的地。

Fluent Bit 在设计时考虑到了高性能和低资源消耗。

2. Fluent Bit 简史

每个项目都有一个故事

2014 年，Treasure Data 的 Fluentd 团队提出了对嵌入式 Linux 和网关等约束环境的轻量级日志处理器的需求，该项目旨在成为 Fluentd 生态系统的一部分，我们称其为 Fluent Bit，完全开源，并在 Apache 许可证 2.0 版本条款下可用。

在项目进行了一段时间后，它在嵌入式市场上获得了一些吸引力，但我们也开始从云社区获得一些特性的请求，比如更多的输入、过滤器和输出。此后不久，Fluent Bit 就成为了解决云环境中日志记录问题的首选解决方案之一。

3. Fluentd & Fluent Bit

生产级生态系统

规模大一些的日志和数据处理通常很复杂，这就是 Fluentd 诞生的原因。现在它不仅仅是一个简单的工具，更是一个完整的生态系统，包含了不同语言和像 Fluent Bit 这样的子项目的 SDK。

在这一页，我们将描述 Fluentd 和 Fluent Bit 开源项目之间的关系，作为一个总结，我们可以说两者都是：

根据 Apache 许可证 2.0 版本的条款许可。
云本地计算基金会（CNCF）主持的项目。
生产级解决方案：每天部署数千次，每月数百万次。
社区驱动的项目。
被业界广泛采用：受到亚马逊、微软、谷歌云等大公司的信任。
最初由 Treasure Data 创建。

这两个项目有很多相似之处，Fluent Bit 完全是在 Fluentd 架构和通用设计的最佳理念之上设计和构建的。选择使用哪个取决于最终用户的需求。

下表描述了不同领域这两个项目的比较：

	Fluentd	Fluent Bit
范围	容器 / 服务器	嵌入式 Linux / 容器 / 服务器
语言	C 和 Ruby	C
内存	约40MB	约650KB
性能	高性能	高性能
依赖	作为 Ruby Gem 构建，主要依赖 gems	零依赖，除非某些特殊插件需要
插件	超过1000个插件可用	大约有70个插件可用
许可	Apache许可证2.0版	Apache许可证2.0版

Fluentd 和 Fluent Bit 都可以作为聚合器或转发器，它们可以相互补充，也可以作为独立的解决方案使用。

4. 许可证

对开放与合作的坚定承诺

Fluent Bit，包括它的核心，插件和工具都是在 Apache 许可证 2.0 版的条款下发布的：
