Enum EscalationLevel 

pub enum EscalationLevel {
    None = 0,
    RejectLowPriority = 1,
    EvictCaches = 2,
    SpillOperators = 3,
    ThrottleMaintenance = 4,
}

The governor’s escalation level under memory pressure, in the exact order of S1E-003 (a higher level implies every lower level’s action stays active). Ordering is derived, so levels compare by escalation severity.

Variants

None = 0

No pressure response.

RejectLowPriority = 1

Step 1: reject new low-priority work.

EvictCaches = 2

Step 2: evict reclaimable caches.

SpillOperators = 3

Step 3: spill eligible query operators (S1E-004 hook point).

ThrottleMaintenance = 4

Step 4: throttle maintenance.
