Arrow Flight SQL Connector Security Guidelines Using SERVER Execution Type - Teradata Fabric

When you connect to Teradata through the Arrow Flight SQL Connector (SERVER execution type):

• The connected Teradata Database uses a JDBC connection to validate your credentials
• To reduce authentication overhead and improve performance, the connector uses a JDBC connection pool
• If a valid pooled connection already exists for your credentials, the connector reuses that connection instead of opening a new JDBC connection
• If no valid pooled connection is available, the connector establishes a new JDBC connection to authenticate your request

This approach improves connection efficiency while the Teradata Database validates your credentials.
