 *  **``batchStallTime``** - how long (ms) to aggregate requests into a
 *  single batch. ``0`` indicates batching will only encompass the current
 *  event loop. If ``batchMaxCount = 1``, this is ignored. (default: ``10``)
 *
 *  **``batchMaxSize``** - target maximum size (bytes) to allow per batch
 *  request (default: 1Mb)
 *
 *  **``batchMaxCount``** - maximum number of requests to allow in a batch.
 *  If ``batchMaxCount = 1``, then batching is disabled. (default: ``100``)
