This section describes how you interact through the  Designer Cloud powered by Trifacta® platform  with Azure® Synapse Analytics (Formerly Microsoft® SQL DW)® .


Limitations

  • Azure Synapse Analytics (Formerly Microsoft SQL DW)  connections are available only if you have deployed the  Designer Cloud powered by Trifacta platform  onto Azure.
  • The defined length of a table row cannot exceed 1 MB.

    NOTE: In this release, this connection cannot be created through the APIs. Please create connections of this type through the application.

Uses of  Azure Synapse Analytics (Formerly Microsoft SQL DW)

The Designer Cloud powered by Trifacta platform  can use Azure Synapse Analytics (Formerly Microsoft SQL DW)  for the following tasks:

  1. Create datasets by reading from Azure Synapse Analytics (Formerly Microsoft SQL DW)  tables.
  2. Write to Azure Synapse Analytics (Formerly Microsoft SQL DW)  tables with your job results.

  3. Ad-hoc publication of data to Azure Synapse Analytics (Formerly Microsoft SQL DW) .

Before You Begin Using  Azure Synapse Analytics (Formerly Microsoft SQL DW)

  • Enable Access: Integration requires the following:

    • Installation of the  Designer Cloud powered by Trifacta platform  on Microsoft Azure.
    • Either ADL or WASB is supported as the base storage layer. For more information, see Set Base Storage Layer.
  • Read Access: Your Azure Synapse Analytics (Formerly Microsoft SQL DW)  administrator must configure read permissions. Your administrator should provide a database for upload.

  • Write Access: You can write and publish jobs results to Azure Synapse Analytics (Formerly Microsoft SQL DW)

Secure Access

These connections require SSL access.

Storing Data in  Azure Synapse Analytics (Formerly Microsoft SQL DW)

Your Azure Synapse Analytics (Formerly Microsoft SQL DW)  administrator should provide database access for storing datasets. Users should know where shared data is located and where personal data can be saved without interfering with or confusing other users. 

NOTE: The Designer Cloud powered by Trifacta platform does not modify source data. Datasets sourced from Azure Synapse Analytics (Formerly Microsoft SQL DW) are read without modification from their source locations.

Reading from  Azure Synapse Analytics (Formerly Microsoft SQL DW)

You can create a Trifacta dataset from a table stored in Azure Synapse Analytics (Formerly Microsoft SQL DW) .

For more information, see Database Browser.

Writing to  Azure Synapse Analytics (Formerly Microsoft SQL DW)

You can write back data to Azure Synapse Analytics (Formerly Microsoft SQL DW)  using one of the following methods:

NOTE: Writing and publishing to Azure Synapse Analytics (Formerly Microsoft SQL DW) is not supported if Azure AD SSO has been enabled.

  • Job results can be written directly to Azure Synapse Analytics (Formerly Microsoft SQL DW)  as part of the normal job execution. Create a new publishing action to write to Azure Synapse Analytics (Formerly Microsoft SQL DW) . See Run Job Page.
  • As needed, you can publish results to Azure Synapse Analytics (Formerly Microsoft SQL DW)  for previously executed jobs.

  • For more information on how data is converted to Azure Synapse Analytics (Formerly Microsoft SQL DW) , see SQL DW Data Type Conversions.

Data Validation issues:

  • No validation is performed for the connection and any required permissions during job execution. So, you can be permitted to launch your job even if you do not have sufficient connectivity or permissions to access the data. The corresponding publish job fails at runtime. 
  • No data validation is performed during writing and publication to Azure Synapse Analytics (Formerly Microsoft SQL DW) . Your job fails if the schema for the Trifacta dataset varies from the target schema.
  • Prior to publication, no validation is performed on whether a target is a table or a view, so the job that was launched fails at runtime.
