1. What is Google File System (GFS)?
Google File System is a scalable distributed file system for large distributed data-intensive applications.
(The Google File System demonstrates the qualities essential for supporting large-scale data processing workloads on commodity hardware)
2. What are the key features of GFS?
- Component failures are the norm rather than the exception;
- Files are huge by traditional standards;
- Most files are mutated by appending new data rather than overwriting existing data;
- Co-designing the applications and the file system API benefits the overall system by increasing our flexibility.
3. What is clustered storage?
When a file system uses clustered storage, it is simultaneously mounted on multiple servers.
