Pluggable caching engine to build and scale high performance cache services. See www.cachelib.org for documentation and more information.
CacheLib is a C++ library providing in-process high performance caching mechanism. CacheLib provides a thread safe API to build high throughput, low overhead caching services, with built-in ability to leverage DRAM and SSD caching transparently.
CacheLib provides a standalone executable CacheBench that can be used to
evaluate the performance of heuristics and caching hardware platforms against
production workloads. Additionally CacheBench enables stress testing
implementation and design changes to CacheLib to catch correctness and
performance issues.
See CacheBench for usage details and examples.
CacheLib has one single version number facebook::cachelib::kCachelibVersion that can be located at CacheVersion.h. This version number must be incremented when incompatible changes are introduced. A change is incompatible if it could cause a complication failure due to removing public API or requires dropping the cache. Details about the compatibility information when the version number increases can be found in the changelog.
CacheLib provides a build script which prepares and installs all dependencies and prerequisites, then builds CacheLib. The build script has been tested to work on CentOS 8, Ubuntu 18.04, and Debian 10.
git clone https://github.com/facebook/CacheLib
cd CacheLib
./contrib/build.sh -d -j -v
# The resulting library and executables:
./opt/cachelib/bin/cachebench --helpRe-running ./contrib/build.sh will update CacheLib and its dependencies
to their latest versions and rebuild them.
See build for more details about the building and installation process.
