Class EncryptedBlobAsyncClient
Please refer to the Azure Docs For Client-Side Encryption for more information.
This client is instantiated through EncryptedBlobClientBuilder
For operations on a specific blob type (i.e. append, block, or page) use getAppendBlobAsyncClient
, getBlockBlobAsyncClient
, or getPageBlobAsyncClient
to construct a client that allows blob specific operations. Note,
these types do not support client-side encryption, though decryption is possible in case the associated
block/page/append blob contains encrypted data.
Please refer to the Azure Docs for more information.

.- Overrides:

encryptionScope
- the encryption scope for the blob, passnull
to use no encryption scope.- Returns:

public EncryptedBlobAsyncClient getCustomerProvidedKeyAsyncClient(CustomerProvidedKey customerProvidedKey) Creates a newEncryptedBlobAsyncClient

- Parameters:

to use no customer provided key.- Returns:
- a
EncryptedBlobAsyncClient
with the specifiedcustomerProvidedKey
.
-
upload
public Mono<BlockBlobItem> upload(Flux<ByteBuffer> data, ParallelTransferOptions parallelTransferOptions) Creates a new block blob. By default, this method will not overwrite an existing blob.Updating an existing block blob overwrites any existing blob metadata. Partial updates are not supported with this method; the content of the existing blob is overwritten with the new content. To perform a partial update of block blob's, use
stageBlock
andBlockBlobAsyncClient.commitBlockList(List)
on a regular blob client. For more information, see the Azure Docs for Put Block and the Azure Docs for Put Block List.The data passed need not support multiple subscriptions/be replayable as is required in other upload methods when retries are enabled, and the length of the data need not be known in advance. Therefore, this method should support uploading any arbitrary data source, including network streams. This behavior is possible because this method will perform some internal buffering as configured by the blockSize and numBuffers parameters, so while this method may offer additional convenience, it will not be as performant as other options, which should be preferred when possible.
Typically, the greater the number of buffers used, the greater the possible parallelism when transferring the data. Larger buffers means we will have to stage fewer blocks and therefore require fewer IO operations. The trade-offs between these values are context-dependent, so some experimentation may be required to optimize inputs for a given scenario.
Code Samples
ParallelTransferOptions parallelTransferOptions = new ParallelTransferOptions() .setBlockSizeLong(blockSize) .setMaxConcurrency(maxConcurrency); client.upload(data, parallelTransferOptions).subscribe(response -> System.out.printf("Uploaded BlockBlob MD5 is %s%n", Base64.getEncoder().encodeToString(response.getContentMd5())));
- Overrides:
upload
in classBlobAsyncClient
- Parameters:
data
- The data to write to the blob. Unlike other upload methods, this method does not require that theFlux
be replayable. In other words, it does not have to support multiple subscribers and is not expected to produce the same values across subscriptions.parallelTransferOptions
-ParallelTransferOptions
used to configure buffered uploading.- Returns:
- A reactive response containing the information of the uploaded block blob.
