  • container the name of the Azure blobstore container to use.
  • storageUrl the Azure storage URL to use. Typically this will be an URL of the form https://<accountName>.blob.core.windows.net/.
  • format the format of the resource referred to by url. CSV/TSV, array wrapped json and line delimited jsons are supported
  • credentials (optional, default = empty) Azure credentials to use for access. Object has the following format: { "accountName": String, "accountKey": String }.
  • maxQueueSize (optional, default = 10) maximum amount of ByteBuffers that can be kept in a queue when downloading a resource. When the queue is full, downloading will halt. Downloading will continue again when a ByteBuffer is dequeued. Usually this value does not need to be overridden, but it can be increased in case downloading halts too often, or decreased to reduce memory use.
