Azure Blob Store

The Azure Blob Store output in ArcGIS Velocity allows you to write output features to files in an Azure Blob Store.

Example

After performing analysis in a big data analytic, a researcher wants to write the output spatial or tabular features to files in an Azure Blob Store.

Usage notes

  • The Dataset parameter specifies the name of the folder to which Velocity will write to the Azure Blob Store. This folder will contain one or more files, depending on the size of the output.
  • Your account key will be encrypted the first time you save your analytic and stored in an encrypted state.
  • When specifying the folder path, use forward slashes (/).
  • This output is only available in big data analytics.
  • Any folder specified in the Folder Path parameter must exist and have content in it before data can be exported to this folder.

Parameters

ParameterDescriptionData type

Account Key

The account access key to access the Azure Blob Store.

Velocity will use the provided account access key to write data to the Azure Blob Store.

String

Folder Path

The folder path of the folder to which the output dataset folder and files should be written. Any folder specified in the Folder Path parameter must exist and have content in it before data can be exported to this folder.

    • /
  • To write the output folder and files to a folder, enter a forward slash followed by the path to the folder—for example:
    • /data_folder
