-------------------------------------
Resolution: Fixed
> Use BinaryType.field() for fast affinity key resolution.

> Key: IGNITE-3829
> URL: https://issues.apache.org/jira/browse/IGNITE-3829
> Project: Ignite
> Issue Type: Task
> Components: cache
> Affects Versions: 1.7
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Labels: performance
> Fix For: 1.8
>
>
> See {{CacheObjectBinaryProcessorImpl.affinityKey}} method. Currently to get
> affinity key field of a regular binary object (i.e. {{BinaryObjectImpl}}), we
> do two heavy things:
> 1) Lookup object type from system cache to get affinity key field name.
> 2) Get that field using {{BinaryObject.field}} method.
> To avoid system cache lookup we should cache resolver affinity field names by
> type ID. To speed field value resolving we should cache not names, but
> {{BinaryField}}.s
