References to Processing Blob and Table Storage services

The Sitecore Cortex™ Processing Engine service's connection strings file stores connection strings for the Sitecore Cortex™ Processing Blob and Table Storage services and associated certificates.  However, the Sitecore Cortex™Processing Engine service accesses the Sitecore Cortex™ Processing Storage database directly and does not use the Sitecore Cortex™ Processing Blob and Table Storage services. The following connection string values are used by the Microsoft Machine Learning Server integration only.

Notes

processing.webapi.blob.mrs.certificate

Connection string should contain path and password for the blob service client authentication certificate. Certificate must be in PKCS #12 (.p12/.pfx) format and must be located on the Microsoft Machine Learning Server compute nodes.

processing.webapi.table.mrs.certificate

Connection string should contain path and password for the table service client authentication certificate. Certificate must be in PKCS #12 (.p12/.pfx) format and must be located on the Microsoft Machine Learning Server compute nodes.

processing.webapi.certificate.authority

Connection string should contain the path to public certificate of certification authority that issued the certificate for the blob and table service endpoints. Certificate must be in Base64 encoded format and must be located on the Microsoft Machine Learning Server compute nodes.

Privacy and security

The Sitecore Cortex™ Processing Engine service handles personal data in the following ways:

  • Processing workers can read contact and interaction data from an xConnect data source.
