Kangaroo: A flash cache optimized for tiny objects (2021)
What the research is: Kangaroo is a new flash cache that enables more efficient caching of tiny objects (objects that are ~100 bytes or less) and overcomes the challenges presented by existing fla…
This admission policy allows Kangaroo to guarantee that the write overhead for moving objects to KSet will be much lower than a set-associative cache. Caching these objects efficiently on flash allows them to be quickly retrieved at scale and minimizes the load on back-end storage services. The authors would like to thank Sara McAllister for leading the project and helping us draft this blog post, and members of the Parallel Data Lab at CMU for their input in guiding the research and collaboration with Facebook.
