      <section><p>Specifies cache key field to be used to determine a node on which given cache key will be stored.
Only one field or property can be marked with this attribute.
<p>
This attribute is an alternative to <a class="xref" href="Apache.Ignite.Core.Binary.BinaryTypeConfiguration.html#Apache_Ignite_Core_Binary_BinaryTypeConfiguration_AffinityKeyFieldName">AffinityKeyFieldName</a> setting.
This attribute has lower priority than <a class="xref" href="Apache.Ignite.Core.Binary.BinaryTypeConfiguration.html#Apache_Ignite_Core_Binary_BinaryTypeConfiguration_AffinityKeyFieldName">AffinityKeyFieldName</a> setting.
<p>
One of the major use cases for this attribute is the routing of grid computations
to the nodes where the data for this computation is cached, the concept otherwise known as 
Colocation Of Computations And Data.
<p>
For example, if a Person object is always accessed together with a Company object for which this person 
is an employee, then for better performance and scalability it makes sense to colocate Person objects 
together with their Company object when storing them in cache. 
To achieve that, cache key used to cache Person objects should have a field or property marked with
<a class="xref" href="Apache.Ignite.Core.Cache.Affinity.AffinityKeyMappedAttribute.html">AffinityKeyMappedAttribute</a> attribute, which will provide the value of 
the company key for which that person works.</p>
