The aim of this tutorial series is to introduce you to programming with persistent, byte-addressable memory using the pmemobj library. We will go over all the available features, implement an example application and learn something about the inner workings of libpmemobj. If you haven’t read …
Read MoreThe PMEMoid plays the role of a persistent pointer in a pmemobj pool. It consist of a shortened UUID of the pool which the object comes from and an offset relative to the beginning of the pool: 1 2 3 4 typedef struct pmemoid { uint64_t pool_uuid_lo; uint64_t off; } PMEMoid; Operating on such …
Read MoreThe focus of the pmemobj library, like the name suggests, is storing objects on a persistent medium. A different, but very common, approach of doing exactly the same is to use a database with a specialized interface to manipulate the collection of data. MySQL is one such database, it processes SQL …
Read MorePersistent memory based storage is able to perform IO at byte (or more accurately, cache line) granularity. However, we often want to expose such storage as traditional block devices. The block drivers for persistent memory will do exactly this. However, they do not provide any atomicity guarantees. …
Read MoreNow that we’ve created the GitHub Repository for the PMDK, here’s a more detailed description of the git workflow we’ve chosen. The basic idea is: Current development happens on the master branch Releases are created periodically by tagging After a major release, a stable-1.x …
