setRelaxOperationTimeoutInHeavyLoadSystem

public void setRelaxOperationTimeoutInHeavyLoadSystem(boolean relaxOperationTimeoutInHeavyLoadSystem)

Description copied from interface: ArcacheConfigurationSetInterface

In heavy loaded systems when CPU is at top, and with too many threads running concurrently, the time measurements are imperfect, because the time is spend in another thread and not in the IO operation. In that cases all the time on a Get operation is spent in the first get of the object key. No timeout is achieved but the seen time of the get operation is much higher than timeout (a signal of overload or a backend bug). In this scenario if the object has invalidation keys is a dilemma, 1. timeout the all the operation, possibly adding more load to the system or 2. relax the timeout and get the invalidation objects

Specified by:

setRelaxOperationTimeoutInHeavyLoadSystem in interface ArcacheConfigurationSetInterface

Parameters:

relaxOperationTimeoutInHeavyLoadSystem - (default true)
