public interface KeyAssociator
A KeyAssociator provides key associations on behalf of a set of keys. The information provided by a KeyAssociator will be used to place all associated keys into the same partition. Custom KeyAssociator implementations should not allow circular associations.
SeeKeyAssociatedFilter
for an example of a distributed query that takes advantage of a custom
KeyAssociator implementation to dramatically optimize its performance.
