CommonOptions

Properties

abortSignal	An implementation of the AbortSignalLike interface to signal the request to cancel the operation. For example, use the @azure/abort-controller to create an AbortSignal.
blockSize	blockSize is the data every request trying to download. Must be greater than or equal to 0. If set to 0 or undefined, blockSize will automatically calculated according to the blob size.
concurrency	Concurrency of parallel download.
conditions	Access conditions headers.
customerProvidedKey	Customer Provided Key Info.
maxRetryRequestsPerBlock	Optional. ONLY AVAILABLE IN NODE.JS. How many retries will perform when original block download stream unexpected ends. Above kind of ends will not trigger retry policy defined in a pipeline, because they doesn't emit network errors. With this option, every additional retry means an additional FileClient.download() request will be made from the broken point, until the requested block has been successfully downloaded or maxRetryRequestsPerBlock is reached. Default value is 5, please set a larger value when in poor network.
onProgress	Progress updater.
tracingOptions	Options to configure spans created when tracing is enabled.
