Asynchronously read multiple record header data for specified keys in one batch call.
Schedule the batch get header command with a channel selector and return.
Another thread will process the command and send the results to the listener in a single call.
If a key is not found, the record will be null. The policy can be used to specify timeouts.
If a batch request to a node fails, the entire batch is cancelled.
