Array and Map should not be wrapped in Nullable #303

Closed heartdance closed 7 months ago

heartdance commented 8 months ago

ClickHouse not support Array or Map wrapped in Nullable. ex: Array(Nullable(String)) is supported, but Nullable(Array(String)) is not supported.

Do you have the opportunity to add an e2e test for your change? And you only need to change the code in spark-3.5, there is a script to backport your change to lower Spark versions' module
