Constructor Detail

DefaultWriteBehindConfiguration

public DefaultWriteBehindConfiguration()

Method Detail

getMinWriteDelay

public int getMinWriteDelay()

Description copied from interface: WriteBehindConfiguration

The minimum number of seconds to wait before writing behind. Lower than or equal to getMaxWriteDelay.

Specified by:

getMinWriteDelay in interface WriteBehindConfiguration

Returns:

Retrieves the minimum number of seconds to wait before writing behind

getMaxWriteDelay

public int getMaxWriteDelay()

Description copied from interface: WriteBehindConfiguration

The maximum number of seconds to wait before writing behind. Greater than or equal to getMinWriteDelay

Specified by:

getMaxWriteDelay in interface WriteBehindConfiguration

Returns:

Retrieves the maximum number of seconds to wait before writing behind

getRateLimitPerSecond

public int getRateLimitPerSecond()

Description copied from interface: WriteBehindConfiguration

The maximum number of write operations to allow per second. Only positive values are legal.

Specified by:

getRateLimitPerSecond in interface WriteBehindConfiguration

Returns:

Retrieves the maximum number of write operations to allow per second.

isWriteCoalescing

public boolean isWriteCoalescing()

Description copied from interface: WriteBehindConfiguration

Whether write operations can be coalesced.

Specified by:

isWriteCoalescing in interface WriteBehindConfiguration

Returns:

Retrieves the write coalescing behavior is enabled or not

getWriteBatchSize

public int getWriteBatchSize()

Description copied from interface: WriteBehindConfiguration

The recommended size of a batch of operations. Only positive values are legal. A value of 1 indicates that no batching should happen. Real batch size will be influenced by arrival frequency of operations and max write delay.

Specified by:

getWriteBatchSize in interface WriteBehindConfiguration

Returns:

Retrieves the size of the batch operation.

getRetryAttempts

public int getRetryAttempts()

Description copied from interface: WriteBehindConfiguration

The number of times the write of a mapping will be retried in the case of failure.

Specified by:

getRetryAttempts in interface WriteBehindConfiguration

Returns:

Retrieves the number of times the write of element is retried.

getRetryAttemptDelaySeconds

public int getRetryAttemptDelaySeconds()

Description copied from interface: WriteBehindConfiguration

A number of seconds to wait before retrying an failed operation.

Specified by:

getRetryAttemptDelaySeconds in interface WriteBehindConfiguration

Returns:

Retrieves the number of seconds to wait before retrying an failed operation.

getWriteBehindConcurrency

public int getWriteBehindConcurrency()

Description copied from interface: WriteBehindConfiguration

A number of bucket/thread pairs configured for this cache's write behind.

Specified by:

getWriteBehindConcurrency in interface WriteBehindConfiguration

Returns:

Retrieves the amount of bucket/thread pairs configured for this cache's write behind

getWriteBehindMaxQueueSize

public int getWriteBehindMaxQueueSize()

Description copied from interface: WriteBehindConfiguration

The maximum number of operations allowed on the write behind queue. Only positive values are legal.
