Abstract: Systems and methods are provided for intent tracking asynchronous operations. An example method can include receiving, at a content management system (CMS), a first request to perform an operation on a content item stored at the CMS; adding the request to perform the operation to a queue of operations to be processed by the CMS; and prior to completing the operation: receiving, from a client device associated with a user account registered at the CMS, a second request to access the content item; in response to the second request, determining a predicted state of the content item, the predicted state of the content item reflecting a result of performing the operation on the content item; and providing, to the client device, a response including the predicted state of the content item.

Abstract: According to some embodiment, a backup storage system receives a request from a client to read a data segment associated with a file object stored in a storage system. In response to the request, the system performs a lookup operation in a first index stored in a memory to identify a first index entry based on a fingerprint of the requested data segment to obtain a first write-evict unit (WEU) identifier (ID) identifying a first WEU storing the requested data segment. The system accesses a solid state device (SSD) operating as a cache memory device to retrieve the data segment from the first WEU. The system extracts and decompresses a compressed data segment retrieved from the first WEU and returns the decompressed data segment to the client without accessing a storage unit for retrieving the same data segment.

Abstract: An example method includes receiving a stream that identifies I/O operations requested to be performed with respect to a data grouping, identifying, in the stream, random I/O requests and sequential I/O requests, queuing the sequential I/O requests in a priority/processing queue and processing the sequential I/O requests immediately without waiting for loading of any metadata, and processing a first one of the random I/O requests and a second one of the random I/O request. When the first and second random I/O requests each depend on the same range of metadata, the first and second random I/O requests are processed in the order received, and when the first and second random I/O requests each depend on different respective ranges of metadata, the first and second random I/O requests are processed at the same time.

Abstract: In one example, a method includes receiving a stream that identifies I/O operations requested to be performed with respect to a data grouping, and identifying, in the stream, random I/O requests and sequential I/O requests. Next, the stream is split into an incoming queue containing the sequential I/O requests and a priority/processing queue containing the random I/O requests. A metadata load queue is then defined by assigning each of the random I/O requests to a respective range of metadata. The metadata of each range is loaded, and the random I/O requests re-queued. Using the loaded metadata, a random I/O operation is performed that corresponds to one of the random I/O requests. Finally, the random I/O operation and a sequential I/O operation are performed concurrently with each other.
