Extending memory capacity with PMEM Databases such as Redis (an in-memory key-value open-source database) consume a lot of memory. Since fast access is essential for them, they use DRAM to store their data. DRAM is quite expensive and has limited capacity, so a solution we propose in this blog post …

At a high level, computing solves problems. These problems, even though different and individual, are sometimes somehow related. A new algorithmic challenge can usually be solved by bringing it down to a well-defined problem with an existing solution. Today, we will be talking about one of such …

Miniasync library provides a framework for the composition and execution of asynchronous tasks in C. To accommodate different user-defined tasks and various types of data that they take in, libminiasync makes use of macros. Using libminiasync for the first time can be challenging.
