SQL databases using JDBC | Databricks on AWS.

In the Spark UI, you can see that the number of partitions dictate the number of tasks that are launched. Each task is spread across the executors, which can increase the parallelism of the reads and writes through the JDBC interface. See the Spark SQL programming guide for other parameters, such as fetchsize, that can help with performance..

Migration Guide: SQL, Datasets and DataFrame - Spark 3.3.0 Documentation.

In Spark 3.0, a 0-argument Java UDF is executed in the executor side identically with other UDFs. In Spark version 2.4 and below, the 0-argument Java UDF alone was executed in the driver side, and the result was propagated to executors, which might be more performant in some cases but caused inconsistency with a correctness issue in some cases..
