    • getBlobBatch

      public BlobBatch getBlobBatch()
      Gets a BlobBatch used to configure a batching operation to send to Azure Storage blobs.
      Returns:
      a new BlobBatch instance.
    • submitBatch

      public Mono<Void> submitBatch(BlobBatch batch)
      Submits a batch operation.

      If any request in a batch fails this will throw a BlobStorageException.

      Code samples

       BlobBatch batch = batchAsyncClient.getBlobBatch();
      
       Response<Void> deleteResponse1 = batch.deleteBlob("container", "blob1");
       Response<Void> deleteResponse2 = batch.deleteBlob("container", "blob2", DeleteSnapshotsOptionType.INCLUDE,
           new BlobRequestConditions().setLeaseId("leaseId"));
      
       batchAsyncClient.submitBatch(batch).subscribe(response -> {
           System.out.println("Batch submission completed successfully.");
           System.out.printf("Delete operation 1 completed with status code: %d%n", deleteResponse1.getStatusCode());
           System.out.printf("Delete operation 2 completed with status code: %d%n", deleteResponse2.getStatusCode());
       }, error -> System.err.printf("Batch submission failed. Error message: %s%n", error.getMessage()));
       
      Parameters:
      batch - Batch to submit.
      Returns:
      An empty response indicating that the batch operation has completed.
      Throws:
      BlobStorageException - If the batch request is malformed.
      BlobBatchStorageException - If any request in the BlobBatch failed.
    • submitBatchWithResponse

      public Mono<Response<Void>> submitBatchWithResponse(BlobBatch batch, boolean throwOnAnyFailure)
      Submits a batch operation.

      If throwOnAnyFailure is true a BlobStorageException will be thrown if any request fails.

      Code samples

       BlobBatch batch = batchAsyncClient.getBlobBatch();
      
       Response<Void> deleteResponse1 = batch.deleteBlob("container", "blob1");
       Response<Void> deleteResponse2 = batch.deleteBlob("container", "blob2", DeleteSnapshotsOptionType.INCLUDE,
           new BlobRequestConditions().setLeaseId("leaseId"));
      
       batchAsyncClient.submitBatchWithResponse(batch, true).subscribe(response -> {
           System.out.printf("Batch submission completed with status code: %d%n", response.getStatusCode());
           System.out.printf("Delete operation 1 completed with status code: %d%n", deleteResponse1.getStatusCode());
           System.out.printf("Delete operation 2 completed with status code: %d%n", deleteResponse2.getStatusCode());
       }, error -> System.err.printf("Batch submission failed. Error message: %s%n", error.getMessage()));
       
      Parameters:
      batch - Batch to submit.
      throwOnAnyFailure - Flag to indicate if an exception should be thrown if any request in the batch fails.
      Returns:
      A response only containing header and status code information, used to indicate that the batch operation has completed.
      Throws:
      BlobStorageException - If the batch request is malformed.
      BlobBatchStorageException - If throwOnAnyFailure is true and any request in the BlobBatch failed.
    • deleteBlobs

      public PagedFlux<Response<Void>> deleteBlobs(List<String> blobUrls, DeleteSnapshotsOptionType deleteOptions)
      Delete multiple blobs in a single request to the service.

      Code samples

       List<String> blobUrls = new ArrayList<>();
       blobUrls.add(blobClient1.getBlobUrl());
       blobUrls.add(blobClient2.getBlobUrl());
       blobUrls.add(blobClient3.getBlobUrl());
      
       batchAsyncClient.deleteBlobs(blobUrls, DeleteSnapshotsOptionType.INCLUDE).subscribe(response ->
               System.out.printf("Deleting blob with URL %s completed with status code %d%n",
                   response.getRequest().getUrl(), response.getStatusCode()),
           error -> System.err.printf("Deleting blob failed with exception: %s%n", error.getMessage()));
       
      Parameters:
      blobUrls - Urls of the blobs to delete. Blob names must be encoded to UTF-8.
      deleteOptions - The deletion option for all blobs.
      Returns:
      The status of each delete operation.
      Throws:
      BlobStorageException - If the batch request is malformed.
      BlobBatchStorageException - If any of the delete operations fail.
    • setBlobsAccessTier

      public PagedFlux<Response<Void>> setBlobsAccessTier(List<String> blobUrls, AccessTier accessTier)
      Set access tier on multiple blobs in a single request to the service.

      Code samples

       List<String> blobUrls = new ArrayList<>();
       blobUrls.add(blobClient1.getBlobUrl());
       blobUrls.add(blobClient2.getBlobUrl());
       blobUrls.add(blobClient3.getBlobUrl());
      
       batchAsyncClient.setBlobsAccessTier(blobUrls, AccessTier.HOT).subscribe(response ->
               System.out.printf("Setting blob access tier with URL %s completed with status code %d%n",
                   response.getRequest().getUrl(), response.getStatusCode()),
           error -> System.err.printf("Setting blob access tier failed with exception: %s%n", error.getMessage()));
       
      Parameters:
      blobUrls - Urls of the blobs to set their access tier. Blob names must be encoded to UTF-8.
      accessTier - AccessTier to set on each blob.
      Returns:
