|
| <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> |
