You can write a custom Spark plugin to traverse the query plan and extract the table scan partition info.

thx for reply, I want to use kyuubi custom eventhandler to trigger subsequent processing. I noticed Kyuubi is mainly Scala. Can custom eventhandler be recognized successfully when written in Java??

Scala and Java should be interoperable, it's technically possible. I don't have much experience in invoking Scala from the Java code, so don't expect me to provide any specific details.
