Method Detail

setDefaultOperationTimeoutMillis

void setDefaultOperationTimeoutMillis(long timeoutMillis)

Parameters:

timeoutMillis - timeoutMillis the default timeout to be used in backend operations

setRelaxOperationTimeoutInHeavyLoadSystem

void setRelaxOperationTimeoutInHeavyLoadSystem(boolean relaxOperationTimeoutInHeavyLoadSystem)

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

Parameters:

relaxOperationTimeoutInHeavyLoadSystem - (default true)

setTimeMeasurementErrorMillis

void setTimeMeasurementErrorMillis(long errorMillis)

Error total en la medicion de tiempos expresado en mili segundos debe ser 1000 + maxClockOffset + maxKeyCreationTime maxClockOffset (diferencia maxima entre 2 relojes de la infraestructura involucrada) maxKeyCreationTime (Tiempo (95pt) que demanda generar un valor a ser almacenado)

Parameters:

errorMillis - the time measurament error in milliseconds

setDefaultInvalidationWindowMillis

void setDefaultInvalidationWindowMillis(long windowMillis)

set the default invalidation window, this is the ammount of time to do probabilistic invalidation.

Parameters:

windowMillis - invalidation window in milliseconds

setDefaultHardInvalidation

void setDefaultHardInvalidation(boolean hardInvalidation)

Parameters:

hardInvalidation - default type of invalidation to be used

setKeyNamespace

void setKeyNamespace(String namespace)

Permite configurar un namsepace default para todas las keys De esta forma se puede evitar la colision de keys con otro servicio

Parameters:

namespace - ...

setKeyDelimiter

void setKeyDelimiter(String keyDelimiter)

Permite configurar un delimitador default para las keys el mismo sera utilizado par separar las keys de invalidacion y el namespace

Parameters:

keyDelimiter - ...

setDefaultExpirationTimeMillis

void setDefaultExpirationTimeMillis(long expirationTimeMillis)

Sets the default value to be used to consider a cached object expired

Parameters:

expirationTimeMillis - ...

setDefaultStoredObjectRemovalTimeMillis

void setDefaultStoredObjectRemovalTimeMillis(long removeTimeMillis)

Sets the default value to be used to set the lifetime of the object at backend level. When this time is reached the object is expected to be removed

Parameters:

removeTimeMillis - ...

setBackendClient

void setBackendClient(ArcacheBackendClient backendClient)

Sets the default backend client to store objects and invalidationkeys

Parameters:

backendClient -

setInvalidationBackendClient

void setInvalidationBackendClient(ArcacheBackendClient invalidationBackendClient)

Set the invalidation backend client to store invalidationkeys If you null this, then the defaultBackendClient is used.

Parameters:

setExpirationProbabilityFunction

void setExpirationProbabilityFunction(ProbabilityFunction expirationProbabilityFunction)

Sets the function to be used to compute the probability of a key has expired

Parameters:

expirationProbabilityFunction -

setInvalidationProbabilityFunction

void setInvalidationProbabilityFunction(ProbabilityFunction invalidationProbabilityFunction)

Sets the function to be used to compute the probability of a key has invalidated

Parameters:

invalidationProbabilityFunction -
