METHODS AND SYSTEMS FOR KEY SHARDING OF OBJECTS STORED IN DISTRIBUTED STORAGE SYSTEM

The present disclosure also provides systems and methods for sharding objects stored in a distributed storage system. In accordance with one embodiment disclosed herein, a key sharding technique is used. Key sharding is an advantageously efficient technique when dealing with an object containing a collection of key-value records. In accordance with an embodiment of the invention, referenced chunks identified by the key shards may each store a subset of the collection of the key-value records, and the key-value records in the subset have key hashes that have a range of matching bits in common. One embodiment disclosed herein provides a method of performing a delta edit of a named object stored in a distributed storage system in which a payload of the named object is stored in key shards. Other embodiments, aspects and features are also disclosed.
