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.
  • The following output data formats are available:
    • Delimited
    • JSON
    • GeoJSON
    • EsriJSON
    • 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 EsriJSON format.

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.

Your account access key will be encrypted the first time you save your analytic 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 to which the files should be written.

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 the root level of an Azure Blob Store, enter a single forward slash—for example:
    • /
  • 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 to which to write will contain the output file or files. The file or files that are written to this folder will be automatically named and broken into multiple files as needed. Do not include file extensions in the dataset name property.

String

Write Mode

The available write modes to write features to files in the Azure Blob Store. The available write modes are as follows:

  • Overwrite
  • Append
  • Error if exists
