我正在使用节俭界面使用 Cassandra 0.6.5。我正在尝试使用 batch_mutate 方法调用，但是，当我执行它时，我没有收到错误消息。这让我相信它有效。当我使用 CLI 检查时，那里什么都没有。我的代码或任何人都可以看到的 mutation_map 格式有问题吗？有任何想法吗？
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);
}
上面的代码产生（列是名称：值@时间戳，值由一个类型组成：和实际值的表示）：
LawOffice : {
Row=08469fba50f448be8943614abd059d10 : {
