Overview of PFS
About PFS
Parallel File System (PFS) is a high-performance semantic file system provided by OBS. It features access latency in milliseconds, TB/s-level bandwidth, and millions of IOPS.
You can access data in a parallel file system via OBS APIs.
Application Scenarios
PFS is highly compatible, scalable, and reliable, and delivers amazing performance.
It is mainly used in the following scenarios:
Big data: log analysis, content recommendation, operation reports, user profiling, and interactive analysis
Using PFS
You can use OBS Console or RESTful APIs to process files stored in PFS anytime, anywhere and retrieve the processed files quickly. PFS supports both Portable Operating System Interface (POSIX) and OBS APIs, so you can process files the same way you process objects. This achieves interoperability between objects and files.
The table below describes the ways to use PFS in detail.
Access permissions for OBS also apply to PFS. Before using PFS, make sure that you have the permissions required to access OBS resources.
