Connection exposes with validate(ValidationDepth) a method for driver-side connection validation. ValidationDepth signals whether it is a local-only validation without incorporating remote communication or whether a full remote validation should be performed. Drivers typically either check the local connection state or send a database message, query or any other mechanism, to validate the connection. Resolves #54.

We should provide a method to test connection validity (connection is open and functional) on the
Connectionlevel. This is useful to test connection liveness without the need to specify a validation-query that might be vendor-specific SQL. Drivers might have a better option to test connection validity than using pure SQL.The method would look like:
Publisher<Void> isValid()We could also include a notion of validation depth (is connected, is the server working) to run validation on two different levels.
This would result in a method signature like:
Publisher<Void> isValid(ValidationDepth)whereValidationDepthis an enum.The text was updated successfully, but these errors were encountered:
