Creating and Reading Files
Explore how clients create and read files in distributed file systems using a client library that manages byte offsets and communicates with the manager. Understand the manager's role in maintaining metadata, handling concurrent file creation with locks, and managing operation logs for reliability. This lesson clarifies key operations in distributed file systems, emphasizing client caching strategies and fault tolerance.
We'll cover the following...
The clients can create and read files from the distributed file system using a GFS client library linked to the application that abstracts some implementation details.
For example, the applications can operate based on byte offsets of files. The client library can translate these byte offsets to the associated chunk index and communicates with the manager to retrieve the chunk handle for the provided chunk index and the location of associated chunk servers. Finally, It contacts the ...
