public final class ParallelTransferOptions

This class contains configuration used to parallelize data transfer operations. Note that not all values are used by every method which accepts this type. Please refer to the javadoc on specific methods for these cases.

Constructor Details

ParallelTransferOptions

public ParallelTransferOptions()

Creates a new ParallelTransferOptions with default parameters applied.

ParallelTransferOptions

@Deprecated
public ParallelTransferOptions(Integer blockSize, Integer maxConcurrency, ProgressReceiver progressReceiver, Integer maxSingleUploadSize)

Deprecated

Use fluent interface to set properties instead.

Creates a new ParallelTransferOptions with default parameters applied.

Parameters:

blockSize - The block size. For upload, The block size is the size of each block that will be staged. This value also determines the number of requests that need to be made. This parameter also determines the size that each buffer uses when buffering is required and consequently amount of memory consumed by such methods may be up to blockSize * numBuffers. For download to file, the block size is the size of each data chunk returned from the service. For both applications, If block size is large, upload will make fewer network calls, but each individual call will send more data and will therefore take longer.
maxConcurrency - The maximum number of parallel requests that will be issued at any given time as a part of a single parallel transfer. This value applies per api. For example, if two calls to uploadFromFile are made at the same time, and each specifies a maxConcurrency of 5, there may be up to 10 outstanding, concurrent requests, up to 5 for each of the upload operations. For buffered uploads only, the maximum number of buffers to be allocated as part of the transfer will be maxConcurrency + 1. In those cases, memory will be allocated lazily as needed. The amount of memory consumed by methods which buffer may be up to blockSize * maxConcurrency. In general, upload methods which do not accept a length parameter must perform some buffering.
progressReceiver - ProgressReceiver
maxSingleUploadSize - If the size of the data is less than or equal to this value, it will be uploaded in a single put rather than broken up into chunks. If the data is uploaded in a single shot, the block size will be ignored. Some constraints to consider are that more requests cost more, but several small or mid-sized requests may sometimes perform better. In the case of buffered upload, up to this amount of data may be buffered before any data is sent. Must be greater than 0. May be null to accept default behavior, which is the maximum value the service accepts for uploading in a single requests, which varies depending on the service.

setBlockSizeLong

public ParallelTransferOptions setBlockSizeLong(Long blockSize)

Sets the block size. For upload, The block size is the size of each block that will be staged. This value also determines the number of requests that need to be made. This parameter also determines the size that each buffer uses when buffering is required and consequently amount of memory consumed by such methods may be up to blockSize * numBuffers. For download to file, the block size is the size of each data chunk returned from the service. For both applications, If block size is large, upload will make fewer network calls, but each individual call will send more data and will therefore take longer.

Parameters:

blockSize - The block size.

Returns:

The ParallelTransferOptions object itself.

setMaxConcurrency

public ParallelTransferOptions setMaxConcurrency(Integer maxConcurrency)

Sets the maximum number of parallel requests that will be issued at any given time.

Parameters:

maxConcurrency - The maximum number of parallel requests that will be issued at any given time as a part of a single parallel transfer. This value applies per api. For example, if two calls to uploadFromFile are made at the same time, and each specifies a maxConcurrency of 5, there may be up to 10 outstanding, concurrent requests, up to 5 for each of the upload operations. For buffered uploads only, the maximum number of buffers to be allocated as part of the transfer will be maxConcurrency + 1. In those cases, memory will be allocated lazily as needed. The amount of memory consumed by methods which buffer may be up to blockSize * maxConcurrency. In general, upload methods which do not accept a length parameter must perform some buffering.

Returns:

The ParallelTransferOptions object itself.

setMaxSingleUploadSizeLong

public ParallelTransferOptions setMaxSingleUploadSizeLong(Long maxSingleUploadSize)

If the size of the data is less than or equal to this value, it will be uploaded in a single put rather than broken up into chunks. If the data is uploaded in a single shot, the block size will be ignored. Some constraints to consider are that more requests cost more, but several small or mid-sized requests may sometimes perform better. In the case of buffered upload, up to this amount of data may be buffered before any data is sent. Must be greater than 0. May be null to accept default behavior, which is the maximum value the service accepts for uploading in a single requests, which varies depending on the service.

Parameters:

maxSingleUploadSize - The threshold value.

Returns:

The ParallelTransferOptions object itself.
