    Escaping Deadlocks in Transactional Databases: Practical Strategies for Real Systems

    Deadlocks aren’t theoretical annoyances they’re workflow killers. In a transactional database, a single deadlock loop can freeze critical operations, force retries at scale, and cripple overall throughput. Teams that treat deadlocks as “rare accidents” eventually pay the price. The reality is simple: if your application uses locks, your system is already vulnerable. 1. Why…

    1. What Context Switching Really Costs Every time the kernel performs a context switch — moving execution from one thread to another — the CPU flushes registers, updates the program counter, and reloads process metadata. This is not “free multitasking.” It burns thousands of CPU cycles.When the switch rate spikes, cache locality is destroyed…
