Description

As discussed in https://github.com/apache/flink/pull/9748:

"For the filter, we calculate these condition UDFs together with other UDFs and do the filter later. I think we can optimize it a bit, i.e., calculate the conditions first and then check whether to call the other UDFs. This can be easily achieved in the SplitRule."
