Overview

Use this account type to connect ELT Snaps with data sources that use ELT Database database accounts. This account type enables you to write transformed data to target databases hosted in the following cloud locations. The JDBC URL you define for your target database indicates the respective cloud location where the database is hosted.

Target DatabaseSupported Cloud LocationCloud Location Indicated in JDBC URL
SnowflakeAWSjdbc:snowflake://<account_name>.snowflakecomputing.com
Microsoft Azurejdbc:snowflake://<account_name>.<region>.azure.snowflakecomputing.com
Google Cloud Platform (GCP)jdbc:snowflake://<account_name>.<region>.gcp.snowflakecomputing.com
RedshiftAWSjdbc:redshift://<redshift-cluster-name>.<region>.redshift.amazonaws.com
Azure SynapseMicrosoft Azurejdbc:sqlserver://<yourserver>.database.windows.net


Note

The ELT Snap Pack does not support mixed accounts from different types of database -types in the same Pipeline. For example, a Pipeline in which some Snaps are connecting to the Snowflake database cannot have other Snaps connecting to the Redshift database.

Prerequisites

A valid Snowflake/, Redshift/, or Azure Synapse database account.

Limitations

  • Supports connecting Connects only to the Snowflake, Redshift, and Azure Synapse databases. 
  • In case of Azure Synapse database, this the ELT database account supports the following:
    • Only provisioned clusters of Azure Synapse, but not in Serverless mode.
    • The following external External locations: 
      • Blob Storage: https://.blob.core.windows.net//
      • ADLS Gen2: https://.dfs.core.windows.net//

titleSpecific Scenarios

When setting default values for the Database Name, Username, and Password fields:

  • As a best practice, ensure that the Default Database Name provided in the Snap's properties and the database name in the JDBC URL field match.

  • Else, make sure that both the database names exist.

     However

However, the username and password from the JDBC URL take precedence over the values provided in the respective fields.
