release of in-memory data caching system , which operates on data in key/value format and is easy to use. Memcached is usually used as a lightweight solution to speed up high-load sites by caching access to the DBMS and intermediate data. Code under the BSD license.
In the new version support for saving cache state between restarts. Memcached can now dump the cache to a file before shutting down (the file is required to be on a RAM disk) and load it the next time it is started, eliminating peaks in the load on content processors due to an empty cache (the cache immediately becomes βwarmβ). The new release also includes using persistent memory devices (persistent-memory, for example NVDIMM) through their mounting using DAX (direct access to the file system bypassing the page cache without using the block device level).
