---------------------------------------

             Summary: Binary objets: Do not use BinaryField when comparing objects with the
same schema.
                 Key: IGNITE-4086
                 URL: https://issues.apache.org/jira/browse/IGNITE-4086
             Project: Ignite
          Issue Type: Task
          Components: binary
    Affects Versions: 1.7
            Reporter: Vladimir Ozerov
             Fix For: 1.8


Most often we perform comparisons of objects with the same schema. When it is so, there is
no need to compare them field-by-field. Instead, we should do the following:
1) Skip header
2) Skip footer
3) Compare byte-by-byte everything in between.

Please ensure that byte-by-byte comparison is implemented efficiently. E.g. that we actually
compare bigger chunks (e.g. 8 bytes at once).
