Abstract
Methods, systems, and computer programs are presented for providing file system functions on a cloud storage system based on blob storage. A cloud storage system comprises storage clusters, and each storage cluster comprises a plurality of storage nodes (each including a partition layer that stores data in blobs organized within containers, and a stream layer for streaming blob data), a hierarchical namespace service for implementing file system functions on the data stored in the blobs and, a front end layer for processing user requests to access and manage data stored on the blobs. The file system functions include flat namespace functions and hierarchical namespace functions. Further, the front end layer accesses the partition layer to access the blobs based on addresses of blobs and accesses the hierarchical namespace service to identify the blobs.
