Abstract
Techniques are generally described related to a flash-based buffer management strategy. One example method for managing a buffer for a computer system may include monitoring, by a buffer management module, a plurality of operations being executed on the computer system and utilizing a plurality of buffer pages of the buffer. The example method may also include, upon a determination that the buffer is full, identifying a specific buffer page from the plurality of buffer pages for eviction, wherein the specific buffer page is selected based on a page state of the specific buffer page and a page hotness prediction for the specific buffer page. The example method may further include evicting the specific buffer page from the buffer.
