Working with business events and RavenDB

About twenty years ago, I remember looking at a typical business application and most of the code was basically about massaging data to and from the database. The situation has changed, but even the most sophisticated of applications today spent an inordinate amount of time just shuffling data around. It may require lot less code, but CRUD still…

Work offloading and controlled parallelism

For a database engine, controlling the amount of work that is being executed is a very important factor for the stability of the system. If we can’t control the work that is being done, it is quite easy to get to the point where we are overwhelmed. Consider the case of a(n almost) pure computational task, which is completely CPU bound. In some…
