Below is a table explaining some specifics around how FIDO interacts with each data source it connects to.

​
Connection Keep Alive Queries

For data source types that support persistent connections, we periodically validate that each connection is still valid. After one minute since the last successful query on that connection, we will run SELECT 1 as result as validation. If this query fails, we will replace that specific connection. Keeping these connections alive and valid helps decrease query latency, providing a better end-user experience.

​
Disabling Keep Alive Queries

For data source types that offer a serverless variety (such as Redshift Serverless), keep alive queries can cost you money because they keep the database awake. We offer the ability to disable keepalives for cases like that. Please reach out to support if you’d like to disable keep alive queries.
