  </h1>
  <div class="markdown level0 summary"><p>Provides affinity information to detect which node is primary and which nodes are
backups for a partitioned cache. You can get an instance of this interface by calling
<a class="xref" href="Apache.Ignite.Core.IIgnite.html#Apache_Ignite_Core_IIgnite_GetAffinity_System_String_">GetAffinity(String)</a> method.
<p>
Mapping of a key to a node is a three-step operation. First step will get an affinity key for 
given key using <code>CacheAffinityKeyMapper</code>. If mapper is not specified, the original key 
will be used. Second step will map affinity key to partition using 
<code>CacheAffinityFunction.partition(Object)</code> method. Third step will map obtained partition 
to nodes for current grid topology version.
<p>
Interface provides various <code>mapKeysToNodes(...)</code> methods which provide node affinity mapping 
for given keys. All <code>mapKeysToNodes(...)</code> methods are not transactional and will not enlist
keys into ongoing transaction.
<p>
All members are thread-safe and may be used concurrently from multiple threads.</p>
