[jira] [Created] (KAFKA-9820) validateMessagesAndAssignOffsetsCompressed allocates batch iterator which is not used

Lucas Bradstreet created KAFKA-9820:
---------------------------------------

             Summary: validateMessagesAndAssignOffsetsCompressed allocates batch iterator which is not used
                 Key: KAFKA-9820
                 URL: https://issues.apache.org/jira/browse/KAFKA-9820
             Project: Kafka
          Issue Type: Bug
          Components: core
            Reporter: Lucas Bradstreet


KAFKA-8106 added a new skip key/value iterator that reduces allocations [https://github.com/apache/kafka/commit/3e9d1c1411c5268de382f9dfcc95bdf66d0063a0].

Unfortunately in LogValidator it creates that iterator but it never uses it, and this is quite expensive in terms of allocations.
