How to use

upload

method

in

com.microsoft.azure.storage.blob.BlockBlobURL

/**
 * Creates a new block blob, or updates the content of an existing block blob.
 * Updating an existing block blob overwrites any existing metadata on the blob. Partial updates are not
 * supported with PutBlob; the content of the existing blob is overwritten with the new content. To
 * perform a partial update of a block blob's, use PutBlock and PutBlockList.
 * For more information, see the
 * <a href="https://docs.microsoft.com/rest/api/storageservices/put-blob">Azure Docs</a>.
 * <p>
 * Note that the data passed must be replayable if retries are enabled (the default). In other words, the
 * {@code Flowable} must produce the same data each time it is subscribed to.
 * <p>
 * For more efficient bulk-upload scenarios, please refer to the {@link TransferManager} for convenience methods.
 *
 * @param data
 *         The data to write to the blob. Note that this {@code Flowable} must be replayable if retries are enabled
 *         (the default). In other words, the Flowable must produce the same data each time it is subscribed to.
 * @param length
 *         The exact length of the data. It is important that this value match precisely the length of the data
 *         emitted by the {@code Flowable}.
 *
 * @return Emits the successful response.
