    Abstract: In one embodiment, an apparatus comprises a storage device and a processor. The storage device stores a feature vector index, wherein the feature vector index comprises a sparse-array data structure representing a feature space for a set of labeled feature vectors, wherein the set of labeled feature vectors are assigned to a plurality of classes. The processor is to: receive a query corresponding to a target feature vector; access, via the storage device, a first portion of the feature vector index, wherein the first portion of the feature vector index comprises a subset of labeled feature vectors that correspond to a same portion of the feature space as the target feature vector; determine the corresponding class of the target feature vector based on the subset of labeled feature vectors; and provide a response to the query based on the corresponding class.

    Abstract: In one embodiment, an apparatus comprises processing circuitry to: receive a request from an application to write an image to a data storage system, the request comprising one or more quality of service parameters indicating a level of service requested by the application; partition the image into a plurality of image parts; upload the plurality of image parts to the data storage system in parallel, wherein if the level of service requested by the application comprises low latency: a plurality of redundant copies of each image part is to be uploaded to the data storage system in parallel; and each image part that fails to upload within an upload timeout threshold is to be re-uploaded to the data storage system; receive an acknowledgment from the data storage system that each image part has been uploaded; and notify the application that the image has been written to the data storage system.
