6.  def clusterResharding(getPartitionIdAndRequestFn: (Set[Address]) ⇒ ToPartitionedMap, getLogicalPartitionIdFn: (Set[Address]) ⇒ (Int) ⇒ Seq[Int]): CustomPartitioningStrategy

   Constructs a ClientCustomStrategy that reshards based on the remote cluster state.

   Constructs a ClientCustomStrategy that reshards based on the remote cluster state.

   This is appropriate for simple custom strategies where you only need to know information about the remote cluster in order to reshard. For example, if you want to be able to add or remove capacity safely.

   Java users should see ClientCustomStrategies$ for an easier to use API.

   getPartitionIdAndRequestFn

   A function that given the current state of the remote cluster, returns a PartialFunction implemented by client that provides the partitioning logic on a request. It takes a Thrift object request, and returns Future Map of partition ids to sub-requests. If we don't need to fan-out, it should return one element: partition id to the original request. This PartialFunction can take multiple Thrift request types of one Thrift service (different method endpoints of one service). Note that this function must be pure (ie referentially transparent). It cannot change based on anything other than the state of the remote cluster it is provided with, or else it will malfunction.

   getLogicalPartitionIdFn

   A function that given the current state of the remote cluster, returns a function that gets the logical partition identifiers from a host identifier, host identifiers are derived from ZkMetadata shardId. Indicates which logical partitions a physical host belongs to, multiple hosts can belong to the same partition, and one host can belong to multiple partitions, for example:

   {
     case a if Range(0, 10).contains(a) => Seq(0, 1)
     case b if Range(10, 20).contains(b) => Seq(1)
     case c if Range(20, 30).contains(c) => Seq(2)
     case _ => throw ...
   }

   Note that this function must be pure (ie referentially transparent). It cannot change based on anything other than the state of the remote cluster it is provided with, or else it will malfunction.

If we don't need to fan-out, it should return one element: partition id to the original request. This PartialFunction can take multiple Thrift request types of one Thrift service (different method endpoints of one service). In this context, the returned partition id is also the shard id. Each instance is its own partition.

    Constructs a ClientCustomStrategy that reshards based on the user provided state.

    This lets the client be aware of the backend dynamic resharding by providing the fully described state of resharding. The partitioning schema needs to be configured to react to each state, and it needs to be a pure function (see param below). When the state got successfully updated, the partitioning strategy will move to the new schema. See clusterResharding if only the backend cluster information needs to be observed in order to reshard.
