Azure Blob Storage Connector

You are looking at an older version of the documentation. The latest version is found here.

The Azure Blob Storage Connector, known by the type name blob, exposes stored procedures to leverage resources stored in Azure Blob Storage.

Connector-specific Connection Properties

Property name	Description
accountName	Azure account name
accountKey	Azure account key
sasToken	SAS token
defaultEndpointsProtocol	Default endpoint protocol
containerName	Name of the Azure container
prefix	The `pathAndPattern` prefix to be used when handling files

sasToken and accountKey are mutually exclusive: either a SAS Token or an Account Key must be specified.

Examples

1. Connecting using an Account Key:

SQL

CALL SYSADMIN.createConnection(name => 'blob', jbossCLITemplateName => 'blob', connectionOrResourceAdapterProperties => 'accountName=<accountName>,accountKey=<accountKey>,defaultEndpointsProtocol=https,containerName=<container name>');;
CALL SYSADMIN.createDataSource(name => 'blob', translator => 'ufile', modelProperties => 'importer.useFullSchemaName=false', translatorProperties => '');;

2. Connecting using a SAS Token:

Example

SQL

CALL SYSADMIN.createConnection(name => 'blob', jbossCLITemplateName => 'blob', connectionOrResourceAdapterProperties => 'accountName=<accountName>,sasToken=<sasToken>,defaultEndpointsProtocol=https,containerName=<container name>');;
CALL SYSADMIN.createDataSource(name => 'blob', translator => 'ufile', modelProperties => 'importer.useFullSchemaName=false', translatorProperties => '');;

Prefix

The prefix allows to limit the result set.

The 'Prefix' property value gets passed in connectionOrResourceAdapterProperties;
All procedures of the connector automatically take the prefix into consideration: e.g., calling listFiles(pathAndPattern => NULL) still applies the prefix from the data source settings;
If the data source has a prefix configured, and a pathAndPattern gets passed, the values get concatenated. For example, if a data source is configured with prefix a/b, and listFiles(pathAndPattern => 'c/d') gets called, this results in a/b/c/d.
