Instance Constructors

  1. new MethodBuilderCustomStrategy(getPartitionIdAndRequest: ToPartitionedMap[Req], responseMerger: Option[ResponseMerger[Rep]])
  2. new MethodBuilderCustomStrategy(getPartitionIdAndRequest: ToPartitionedMap[Req])
  3. new MethodBuilderCustomStrategy(getPartitionIdAndRequest: ToPartitionedMap[Req], getLogicalPartitionId: (Int) ⇒ Seq[Int])
  4. new MethodBuilderCustomStrategy(getPartitionIdAndRequest: ToPartitionedMap[Req], getLogicalPartitionId: (Int) ⇒ Seq[Int], responseMerger: Option[ResponseMerger[Rep]])

    getPartitionIdAndRequest

    A function for the partitioning logic. MethodBuilder is customized per-method so that this method only takes one Thrift request type.

    getLogicalPartitionId

    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:

    val getLogicalPartition: Int => Seq[Int] = {
  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 ...
}

    If not provided, the default is that each instance is its own partition.

    responseMerger

    Supplies a ResponseMerger for messaging fan-out. Non-fan-out case the default is None.
