Apache Mnemonic is a non-volatile hybrid memory storage oriented library and it proposes a non-volatile/durable Java object model and durable computing service that bring several advantages to significantly improve the performance of massive real-time data processing/analytics and helps to build cache-less and SerDe-less high performance applications. Mnemonic has two memory service based on “NVML”. On december 2017 NVML has changed it’s name into PMDK and has also started growing its libraries and tools. So, we need to upgrade Mnemonic volatile and nonvolatile memory service according to PMDK libraries. PMDK is tuned and validated on both Linux and Windows, the libraries build on the DAX feature of those operating systems which allows applications to access persistent memory as memory-mapped files, as described in the SNIA NVM Programming Model.
