Fields

partition_leader_epoch: i32

magic: i8

crc: u32

attributes: i16

last_offset_delta: i32

Indicates the count from the beginning of the batch to the end

Adding this to the base_offset will give the offset of the last record in this batch

first_timestamp: i64

max_time_stamp: i64

producer_id: i64

producer_epoch: i16

first_sequence: i32
