Abstract: Embodiments prefetch read caches based on usage patterns. A workload session associated with one or more requests may be employed to perform actions, including: collecting one or more pattern handlers associated with an identifier of the workload session and a file system item; collecting one or more locations of data designated for promotion from a source cache to a target cache based on the one or more pattern handlers' evaluation of a usage pattern associated with the workload session; collecting one or more prefetch requests from the one or more pattern handlers, wherein each prefetch request includes one or more portions of the one or more locations; executing one or more prefetch jobs to promote the data designated for promotion from the source cache to the target cache; or the like.

Abstract: Embodiments are directed to bandwidth management in distributed file systems. A request stored in a queue may be dequeued. A work credit value may be determined based on a duration since a last job and a work rate associated with the file system such that the work credit value conforms to a maximum threshold value. A job may be initialized based on the dequeued request such that the work credit value may be reduced based on a size of the job. In response to the reduced work credit value being a negative value further actions may be performed, including: determining a time delay based on the reduced work credit value, the work rate, and the size of the job; delaying an execution of the job until the expiry of the time delay such that upon expiry of the time delay, the job is executed to satisfy the request.

Abstract: A file system with distributed resource caching that includes cache volumes and agents that may be associated with clients of the file system may be provided. A cache allocation for each agent may be determined based on a capacity of the cache volumes and a number of the agents such that each cache allocation is associated with tokens that each represents a reserved portion of free space in the cache volumes. Storage jobs may be provided to the agents. Data associated with the storage jobs may be stored in the cache volumes. The cache allocation for each agent may be reduced based on the data stored for each agent.
