List of mapKeys() Examples

Examples of mapKeys()

com.linkedin.d2.balancer.KeyMapper.mapKeys()
Maps keys to hosts according to the underlying strategy, e.g., consistent hashing. Output is a map of host URI to group of keys. Each key in the input set will appear in exactly one of output groups, i.e., the groups are mutually exclusive and collectively exhaustive (MECE). Duplicate keys are allowed. @param keys The set of keys to be mapped @param serviceUri The URI for the service to which requests will be issued @param < K> The key type @return map of host URI -> mapped keys @deprecated use @link #mapKeysV2(URI, Collection) instead
