public class EncryptedBlobAsyncClient
extends BlobAsyncClient
This class provides a client side encryption client that contains generic blob operations for Azure Storage Blobs. Operations allowed by the client are uploading, downloading and copying a blob, retrieving and setting metadata, retrieving and setting HTTP headers, and deleting and un-deleting a blob. The upload and download operation allow for encryption and decryption of the data client side. Note: setting metadata in particular is unsafe and should only be done so with caution.
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.

upload
public Mono
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 and BlockBlobAsyncClient#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:
EncryptedBlobAsyncClient.upload(Flux<ByteBuffer> data, ParallelTransferOptions parallelTransferOptions)Parameters:

be replayable. In other words, it does not have to support multiple subscribers and is not expected
to produce the same values across subscriptions.
