I find there are many parameters in training phase. Have you run this project on large datasets, like SIFT1M(even SIFT1B) and GIST1M? And how to choose the appropriate parameters? Thanks...

请问DjangoX和xadmin是什么关系？

readme中说是继承和拓展，不过两个项目的代码结构看起来的并不相同，是同一个团队的吗？而且DjangoX最近更新已经是三个月前了，xadmin却三天前还在更新啊

TsFile的写法

1

T和F大写的`TsFile`是否是正确写法？如果是，在`TsfileDBConfig`应该整体重命名一下

FileNodeProcessor的action问题

1

FileNodeProcessor会向下传递三个action，在close的时候会用到 其中的两个：  close是同步操作，在`recordWriter.close()`之后可以结束，然后在FileNode的close函数中完成这两个操作，似乎没有必要下放到这里完成。

BufferWrite的restore的action

1

line 114，这里备份的lastUpdateTimeMap是一个map数组，应该深拷贝，否则这里备份了仍然会被外界修改，没有意义 ``` private Action bufferwriteCloseAction = new Action() { @Override public void act() throws Exception { // update the lastUpdatetime, newIntervalList and Notice: thread // safe synchronized (fileNodeProcessorStore) {...

overflowNameSpaceSet的更改不能达到目的

1

`cn.edu.tsinghua.iotdb.engine.filenode.FileNodeManager`中，`addNameSpaceToOverflowList`函数会在每个FileNode增删改操作时被执行，overflowNameSpaceSet中是当前所有被更改过的nameSpacePath。 但是，`overflowBackUpAction`和`overflowFlushAction`两个函数（line62，72）是在某个FileNode的flush之前先备份一下，flush结束后刷写备份前的set，这样做似乎欠考虑。
