public class PreallocatedCircuitBreakerService
extends CircuitBreakerService
implements org.elasticsearch.core.Releasable

CircuitBreakerService that preallocates some bytes on construction. Use this when you know you'll be allocating many small things on a CircuitBreaker quickly and there is a definite "finished" time, like when aggregations are built.
