/**
 * Runtime binding for the `DecreaseReplicationFactor` operation (IAM action
 * `dax:DecreaseReplicationFactor`), scoped to one {@link Cluster}.
 *
 * Removes read-replica nodes from the bound DAX cluster — the scale-in half
 * of node-count automation (e.g. shrinking a cluster off-peak to cut
 * node-hour cost). Provide the implementation with
 * `Effect.provide(AWS.DAX.DecreaseReplicationFactorHttp)`.
 * ### Scaling a Cluster
 * **Example:** Scale In to One Node
 * ```typescript
 * const decreaseReplicationFactor =
 *   yield* DAX.DecreaseReplicationFactor(cluster);
 *
 * const result = yield* decreaseReplicationFactor({
 *   NewReplicationFactor: 1,
 * });
 * // result.Cluster?.TotalNodes → 1 once the removal completes
 * ```
