> 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
> Labels: performance
> 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).
