Syntho Beta feature
Important
This connector can only be used as a source database. The generated data can be written to Azure Data Lake Storage (ADLS) or Amazon Simple Storage Service (S3) as Parquet files.
Before you begin, gather this connection information:
Name of the server that hosts the database you want to connect to and port number
User name and password
Are you connecting to an SSL server?
Launch Syntho and select Connect to a database, or under Create workspace, select Hive. For a complete list of data connections, select More under From database. Then do the following:
Enter the name of the server that hosts the database and the port number to use.
Optionally, enter the schema name.
Enter user name and password.
Select the Require SSL check box when connecting to an SSL server.
Select Create Workspace.
If Syntho can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact your network administrator or database administrator.

To address this, use the partitioning columns along with the additional columns specified through the "ORDER BY" dropdown. This approach ensures unique and consistent ordering, leveraging both the partitioning logic and user-defined columns. For more information, check in table settings.
