The distributed lock system prioritizes strong consistency, fault tolerance, and safety over availability, ensuring no two pods can hold the same lock even under failures or network partitions
That distinction usually clicks only after you’ve lived through it in production. Leader election reduces coordination noise, while per-task locks solve local correctness,mixing them is where systems get brittle.
And yeah, TTL issues at 3am are almost always about renewal gaps, GC pauses, or assuming clocks behave , that’s why I’m a big fan of lease-based locks with explicit heartbeats and conservative TTLs.
