You can download the latest Databricks JDBC here (https://www.databricks.com/spark/jdbc-drivers-download) in which the latest Arrow version is 17 (https://databricks-bi-artifacts.s3.us-east-2.amazonaws.com/simbaspark-drivers/jdbc/2.7.1/docs/releas...).
We encourage you not to turn off Arrow, which has severe performance degradation. Instead, you can apply the following JVM parameters, as it is also called out in the driver configuration and installation guide (https://docs.databricks.com/aws/en/assets/files/Databricks-JDBC-Driver-Install-and-Configuration-Gui... or you can find it embedded in the driver package).
