A system for estimating one or more data storage parameters and/or statistics in a data storage system is presented. The data storage system includes a plurality of storage containers. The system includes a snapshot module, a container stats aggregator, a synchronization module, a global stats aggregator, and storage stats estimator.

Event based aggregation for distributed scale-out storage systems

A file system may include an object storage, a merged index, and a distributed database. When a file is stored in the file system, the file may be converted to an object and be stored in the object storage. The deduplication index of the file may be stored in the distributed database. The namespace metadata of the file may be stored in the merged index. The merged index generates namespace entries of the file when the file is created, deleted, and/or modified. A namespace entry may be associated with a specific file and may include a creation version and a deletion version. When a file is deleted or modified, instead of modifying the existing namespace entries, new entries associated with different versions and including different creation or deletion versions are created. The status of a file may be monitored by one or more entries associated with a file.

Deduplicated merged indexed object storage file system

Aspects of the current patent document include systems and methods to perform search in an index system. In one embodiment, an index system may be implemented in an object storage. A distributed database index is used in conjunction with the object storage. In some cases, data stored in the distributed database may be encrypted and moved to object storage. The object storage stores a plurality of blocks containing words. Each block can contain a large number of words, such as one million words.
