| <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> |
