Abstract
An exemplary method includes receiving a request to store a data item within a directory of a virtual file structure layer for an unstructured storage layer of a data storage system, caching an identifier of a collection object representative of the directory, sending a query to a plurality of storage nodes included in a cluster of the data storage system, receiving, in response to the query, replies from a subset of the storage nodes that are available to store the data item, selecting, based on the replies, a storage node from the subset of storage nodes, transmitting the data item to the selected storage node for storage by the selected storage node within the unstructured storage layer, accessing, based on the cached identifier, the collection object, and updating the collection object to include a reference to the data item stored in the selected storage node.
