RavenDB is a pretty big system, with well over 1 million lines of code. Recently, I had to deal with an interesting problem. I had a CancellationToken at hand, which I expected to remain valid for the duration of the full operation.However, something sneaky was going on there. Something was cancelling my CancelationToken, and not in an expected manner. At last count, I had roughly 2 bazillion CancelationTokens in the RavenDB codebase. Per request, per database, global to the server process, time-based, operation-based, etc., etc.Figuring out why the CancelationToken was canceled turned out to be a chore. Instead of reading through the code, I cheated.token.Register(() => { Console.WriteLine("Cancelled!" + Environment.StackTrace); });I ran the code, tracked back exactly who was calling cancel, and realized that I had mixed the request-based token with the database-level token. A single line fix in the end. Until I knew where it was, it was very challenging to figure it out.This approach, making the code tell you what is wrong, is an awesome way to cut down debugging time by a lot.

Cloud service costs can often be confusing and unpredictable.RavenDB Cloud's new feature addresses this by providing real-time cost predictions whenever you make changes to your system. This transparency allows you to make informed choices about your cluster and easily incorporate cost considerations into your decision loop to take control of your cloud budget.. The implementation of cost transparency and visibility features within RavenDB Cloud has an outsized impact on cost management and FinOps practices. It empowers you to make informed decisions, optimize spending, and achieve better financial control.The idea is to make it easier for you to spend your money wisely. I’m really happy with this feature. It may seem small, but it will make a difference. It also fits very well with our overall philosophy that we should take the burden of complexity off your shoulders and onto ours.
