 Valkey 8.0 GA is around the corner and one of the themes is increasing overall memory efficiency. Memory overhead reduction has the obvious effect of better resource utilization, but also impacts performance. By minimizing unnecessary memory consumption, you can store more data with the same hardware resources and improve overall system responsiveness. This post is going to give an overview into how Valkey internally manages the data and its memory overhead. Additionally, it talks about the two major improvements for Valkey 8.0 that improves the overall memory efficiency.

  In the [first part](/blog/unlock-one-million-rps/) of this blog, we described how we offloaded almost all I/O operations to I/O threads, thereby freeing more CPU cycles in the main thread to execute commands. When we profiled the execution of the main thread, we found that a considerable amount of time was spent waiting for external memory. This was not entirely surprising, as when accessing random keys, the probability of finding the key in one of the processor caches is relatively low.  Considering that external memory access latency is approximately 50 times greater than L1 cache, it became clear that despite showing 100% CPU utilization, the main process was mostly “waiting”. In this blog, we describe the technique we have been using to increase the number of parallel memory accesses, thereby reducing the impact that external memory latency has on performance.
