## What it is
Baidu File System (BFS) is a distributed file system written in C++ designed for real-time applications, offering fault tolerance, low read/write latency, and high throughput. It uses Raft for metadata consistency and supports multi-datacenter deployment with up to 10,000 data nodes.

## Use cases
- store and serve files for real-time search indexing systems
- run a fault-tolerant distributed file system with low latency
- replace HDFS for workloads needing low-latency reads and writes
- deploy a scalable file system across multiple data centers
- back user behavior analytics pipelines with shared storage

## When to choose
- you need a distributed file system optimized for low-latency real-time workloads rather than batch processing
- you want Raft-based metadata consistency with no single point of failure
- you operate large Linux C++ clusters and can build from source

## When to avoid
- you need a general-purpose POSIX file system for desktop use
- you want a mature, actively maintained project - the last release was 2018
- you need Hadoop ecosystem integration out of the box

## Facets
- artifact type: service
- maturity: maintenance
- function: file-system, caching, streaming
- domain: microservices, big-data, infrastructure-as-code
- platform: cpp
- tags: distributed-file-system, raft, low-latency, high-throughput, storage, linux
