> SPARK-18016 introduced an arbitrary threshold for the size of a generated class (https://github.com/apache/spark/blob/83488cc3180ca18f829516f550766efb3095881e/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/codegen/CodeGenerator.scala#L286). This value is hardcoded.
> Since this is just a guess, in some cases making it smaller can help avoiding the error of exceeding the maximum number of entries in the Constant Pool.
> Then, I suggest to introduce a new configuration parameter, which defaults to the previous value, but it allows to set this to a smaller one if needed.
