A deadlock occurs when two transactions block each other because each is waiting for a resource the other one holds. Consistent lock ordering in application code, short transactions, and robust retry logic prevent most deadlocks before the database ever has to step in.

Every plugin increases memory usage, extends startup time, and can slow the IDE down. The question is not which plugins exist, but which ones genuinely add value to your own workflow, and which ones can be disabled without any loss.

Loading data directly from the database inside GraphQL resolvers quickly produces hundreds of individual queries per request once fields get nested. The DataLoader Pattern collects these loading requests within a single tick, executes them as one batch, and caches the results per request, without forcing resolvers to give up their simple, isolated structure.

A deadlock log entry looks like cryptic noise at first glance, but it contains all the information needed to reconstruct the cause precisely. Analyzing deadlocks from logs systematically, instead of dismissing them as rare chance events, reveals the underlying lock order in the code and fixes it permanently instead of just waiting for the next reconnect.
