birschick-bq opened a new issue, #2280: URL: https://github.com/apache/arrow-adbc/issues/2280
### What happened? When running the (integration) tests, the `ClientTests.CanExecuteUpdate` and `DriverTests.CanExecuteUpdate` can concurrently try to create and update the same test table. This can lead to flakey test failures and in the worst case leave the Databricks server in an inconsistent state (resource leaks). ### Stack Trace ``` Message: System.AggregateException : One or more errors occurred. (Error running query: io.delta.exceptions.ConcurrentAppendException: Files were added to the root of the table by a concurrent update. Please try the operation again.

Using VS, invoke the tests for `Apache.Arrow.Adbc.Tests.Drivers.Apache.Spark` level. ### Environment/Setup _No response_ -- This is an automated message from the Apache Git Service.
