It is widely believed that a distributed cache is a simple way to make everything faster. But if my past experience is any guide, cache misuse can make things even worse.   Let’s examine a few potential scenarios under which a poorly implemented cache could hurt, not help, performance.   Scenario one: Issue: My database lags, and with your cache it slows down even How does a…

In last week's post, "Distributed data structures: Part 1 (overview),"I talked about why you need distributed data structures (hereinafter - RSD) and disassembled several options offered by the distributed cache Apache Ignite. Today I want to talk about the details of the implementation of specific RSD, as well as a small educational program on distributed caches. To begin with, at least in the…

Modern applications, however, tend to use all available resources, in particular, all available CPUs. Unfortunately, it is not possible to use standard data structures for multithreaded processing, so Java 5…
