Yes, you’ve heard this correctly. This is precisely a detective story, even a few stories. Each of them has an intricate plot, several active (or inactive) persons, facts, clues, and evidence. During the session, we will solve all these cases and complete a path from obtaining information (accurate or inaccurate) to a complete understanding and solution of the problem, which will allow you to feel confident in a similar situation and work more efficiently with SQL Server. I cannot disclose many details so far (you understand), but I can tell that the topics of performance tuning, blocking and server management will take part in this detective, and the stories themselves are true.
