Abstract
Techniques for implementing a shared data cache for kernel bypass applications are provided. In one set of embodiments, a shared data caching (SDC) service associated with an instance of a kernel bypass application can create a named shared memory region in user space, where the kernel bypass application is configured to use a user-level Input/Output (I/O) stack for accessing a physical I/O device. The SDC service can further map the named shared memory region into a virtual memory address space of the instance. Then, at a time the instance issues an I/O read request to the physical I/O device, the SDC service can process the I/O read request by accessing the named shared memory region as a data cache.
