我使用thrift接口使用Cassandra 0.6.5。我试图使用batch_mutate方法调用，但是，当我执行它时，我没有收到任何错误消息。这让我相信它有效。当我使用CLI检查时，没有任何内容。我的代码或者mut_map的格式是否有问题，任何人都可以看到？有什么想法吗？
提前致谢，

public void Update(string keyspace, Common.NetworkPackage.MetaAsset ma)
{
Dictionary<string, Dictionary<string, List<Mutation>>> package;
Dictionary<string, List<Mutation>> packageEntry;
Dictionary<string, object>.Enumerator en;
List<Mutation> mutList;
Mutation mut;
DateTime now = DateTime.Now;
if(!ma.Fields.ContainsKey("$guid"))
throw new ArgumentException("The field $guid is not present");
mutList = new List<Mutation>();
en = ma.Fields.GetEnumerator();
while(en.MoveNext())
{
if (en.Current.Value == null)
continue;
mut = new Mutation();
mut.Column_or_supercolumn = new ColumnOrSuperColumn();
mut.Column_or_supercolumn.Column = new Column();
mut.Column_or_supercolumn.Column.Name = _utf8.GetBytes(en.Current.Key);
if (en.Current.Value == null)
mut.Column_or_supercolumn.Column.Value = null;
else
mut.Column_or_supercolumn.Column.Value = ToBytes(en.Current.Value);
mut.Column_or_supercolumn.Column.Timestamp = Utilities.Timestamp(now);
mutList.Add(mut);
}
packageEntry = new Dictionary<string, List<Mutation>>();
packageEntry.Add("MetaAsset", mutList);
package = new Dictionary<string, Dictionary<string, List<Mutation>>>();
package.Add((string)ma.Fields["$guid"], packageEntry);
Console.WriteLine(Utilities.ExportBulkMutate("LawOffice", package));
_client.batch_mutate(keyspace, package, ConsistencyLevel.QUORUM);
}
上面的代码生成（列是name：value @ timestamp，value由一个类型：和实际值的表示形式）：
LawOffice : {
Row=08469fba50f448be8943614abd059d10 : {
CF=MetaAsset : {
