ClientPartitionAwarenessMapper (Ignite 2.17.0)

```
public interface ClientPartitionAwarenessMapper
```
This function calculates the cache key to a partition mapping for each cache key. It is used only for local calculation on a client side.
When the ClientConfiguration.isPartitionAwarenessEnabled() and the cache was created with a custom AffinityFunction or a AffinityKeyMapper this function will be used to calculate mappings. Be sure that a key maps to the same partition produced by the AffinityFunction.partition(Object) method.

Since:

2.14
