Do java UDTF's support parallel streams?
I am wondering if Java UDTF's support parallel streams for better throughput and performance compared to Python UDTF's.

- Yes, Java UDTF's support parallel streams for better throughput and performance.
- Java doesn’t have the Global Interpreter Lock (GIL) problem like Python, allowing multiple inputs to be parallelized.
- For a single SQL query in RisingWave, it can be parallelized into multiple streams, so Java UDF should not be bottlenecked.
