示例1: sendBatch
// sendBatch unrolls a batched command and sends each constituent
// command in parallel.
// TODO(tschottdorf): modify sendBatch so that it sends truly parallel requests
// when outside of a Transaction. This can then be used to address the TODO in
// (*TxnCoordSender).resolve().
func (tc *TxnCoordSender) sendBatch(ctx context.Context, batchArgs *proto.BatchRequest, batchReply *proto.BatchResponse) {
// Prepare the calls by unrolling the batch. If the batchReply is
// pre-initialized with replies, use those; otherwise create replies
// as needed.
// TODO(spencer): send calls in parallel.
batchReply.Txn = batchArgs.Txn
for i := range batchArgs.Requests {
args := batchArgs.Requests[i].GetValue().(proto.Request)
if err := updateForBatch(args, batchArgs.RequestHeader); err != nil {
batchReply.Header().SetGoError(err)
return
}
call := proto.Call{Args: args}
// Create a reply from the method type and add to batch response.
if i >= len(batchReply.Responses) {
call.Reply = args.CreateReply()
batchReply.Add(call.Reply)
} else {
call.Reply = batchReply.Responses[i].GetValue().(proto.Response)
