What Is Pod Priority?
Pod priority is an integer assigned through a priority class that ranks pods by importance. The scheduler favors higher-priority pods when placing work, and under resource pressure lower-priority pods can be evicted to make room. It is the basis for preemption decisions.
Why it matters
Priority lets critical workloads win scheduling over best-effort batch jobs on a busy cluster. Setting it wrong can starve important services or let cheap jobs evict them.
