Returns the number of seconds to delay the store writes.

Returns:

the number of delay seconds.

setWriteDelaySeconds

public MapStoreConfig setWriteDelaySeconds(int writeDelaySeconds)

Sets the number of seconds to delay before writing (storing) the dirty records

Default value is 0.

Parameters:

Default value is 1.

Parameters:

writeBatchSize - the number of operations to be included.

isEnabled

public boolean isEnabled()

Returns if this configuration is enabled

Returns:

true if enabled, false otherwise

setEnabled

public MapStoreConfig setEnabled(boolean enabled)

Enables and disables this configuration

Parameters:

enabled -

setImplementation

public MapStoreConfig setImplementation(Object implementation)

Sets the map store implementation object

Parameters:

implementation - implementation object

Returns:

this MapStoreConfig instance

getImplementation

public Object getImplementation()

Returns the map store implementation object

Returns:

map store implementation object

setFactoryImplementation

public MapStoreConfig setFactoryImplementation(Object factoryImplementation)

setProperty

public MapStoreConfig setProperty(String name,
                                  String value)

getProperty

public String getProperty(String name)

Parameters:

initialLoadMode - initial load mode object

isWriteCoalescing

public boolean isWriteCoalescing()

Returns true if write-coalescing is enabled.

Returns:

See Also:

setWriteCoalescing(boolean)

setWriteCoalescing

public void setWriteCoalescing(boolean writeCoalescing)

Setting writeCoalescing is meaningful if you are using write-behind MapStore.

When writeCoalescing is true, only the latest store operation on a key in the writeDelaySeconds time-window will be reflected to MapStore.

Default value is true.

Parameters:

writeCoalescing - true to enable write-coalescing, false otherwise.
