Embodiments are directed to managing data in a file system. An engine may receive read requests associated with a file system that includes pre-fetch storage and file storage. The engine may employ a pre-fetch policy selected from a plurality of pre-fetch policies to copy blocks to pre-fetch storage. The engine may evaluate the selected pre-fetch policy and also evaluate simulated performances for each unselected pre-fetch policy based on subsequent read requests. The engine may provide a performance score based on the evaluation of the selected pre-fetch policy and it may provide other performance scores based on the simulated evaluation of each unselected pre-fetch policy If one of the other performance scores for one of the unselected pre-fetch policies exceeds the performance score of the selected pre-fetch policy, the engine may select that unselected pre-fetch policies as a new selected pre-fetch policy.

The present invention relates generally to file systems, and more particularly, but not exclusively, to managing pre-fetching in a distributed file system environment.
Modern computing often requires the collection, processing, or storage of very large data sets or file systems. Accordingly, to accommodate the capacity requirements as well as other requirements, such as, high availability, redundancy, latency/access considerations, or the like, modern file systems may be very large or distributed across multiple hosts, networks, or data centers, and so on. Conventionally, some distributed file systems implement various pre-fetching schemes to help improve read performance. However, implementing a pre-fetch policy that consistently or predictably improves read performance may be difficult because of the variability of client read patterns. Thus, it is with respect to these considerations and others that the present invention has been made.
Non-limiting and non-exhaustive embodiments of the present innovations are described with reference to the following drawings. In the drawings, like reference numerals refer to like parts throughout the various figures unless otherwise specified. For a better understanding of the described innovations, reference will be made to the following Detailed Description of Various Embodiments, which is to be read in association with the accompanying drawings, wherein:
FIG. 1 illustrates a system environment in which various embodiments may be implemented;
FIG. 2 illustrates a schematic embodiment of a client computer;
Various embodiments now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. The embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Among other things, the various embodiments may be methods, systems, media or devices. Accordingly, the various embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment, though it may. Furthermore, the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the invention.
In addition, as used herein, the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise. The term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”
