> Since 'org.apache.iceberg.expressions.InclusiveMetricsEvaluator.MetricsEvalVisitor#notIn' [https://github.com/apache/iceberg/blob/master/api/src/main/java/org/apache/iceberg/expressions/InclusiveMetricsEvaluator.java#L370] always returns 'ROWS_MIGHT_MATCH', the push-down of NOT_IN was not implemented at that time, but NOT_IN works when the column is a partitioned column, it's still very helpful.
