Abstract
Techniques for implementing selective file system caching are disclosed. In one particular embodiment, the techniques may be realized as a method including receiving an I/O request from an application such that the application provides a no-cache indication to a file system to implement a direct. I/O for the I/O request, comparing the I/O request and the no-cache indication with a configurable cache map such that the configurable cache map indicates a selective caching based on an I/O type and a file type, processing the I/O request to render a caching decision based on the comparison, and executing selective caching on the I/O request in accordance with the caching decision.
