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

Keep the following in mind when working with the Azure Blob Store output:

• 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.
• The account key is encrypted the first time an analytic is saved 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 contain content before data can be exported to it.
• The following output data formats are available:
  • Delimited
  • JSON
  • GeoJSON
  • Esri JSON
  • Parquet
  • Shapefile
• Data exported in a delimited format will include SHAPE and DATE fields. The SHAPE field will contain geometry in WKT format. The DATE field is provided if the data includes a START_TIME key field.
• Data exported in the JSON format will provide geometry in the Esri JSON format.

Parameters

The following are the parameters for the Azure Blob Store:

Parameter	Description	Data type
Account Key	The account access key for the Azure Blob Store. Velocity uses the account access key to write data to the Azure Blob Store. The account access key is encrypted the first time an analytic is saved and stored in an encrypted state.	String
Account Name	The name of the Azure Storage Account that contains Azure Blob Store containers.	String
Endpoint Suffix	The endpoint suffix used to access the Azure Blob Store. For most users, this will be core.windows.net.	String
Container Name	The name of the Azure Blob Store container where the files will be written.	String
Folder Path	The folder path of the folder to which the output dataset folder and files will be written. Any folder specified must exist and contain content before data can be exported to it. To write the output folder and files to the root level of an Azure Blob Store, enter a single forward slash (/). 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	String
Dataset	The name of the folder that will contain the output file or files. The file or files that are written to this folder will be automatically named and divided into multiple files as needed. Do not include file extensions in the dataset name.	String
Write Mode	The write modes that can be used to write features to files in the Azure Blob Store. The following are the available write modes: Overwrite Append Error if exists	String
