It is helpful. We are using LZ4 and are encountering the same performance issue caused by this. I hope this will be merged as soon as possible.

#416 中对这一问题进行了一定了的修复，请基于此重新进行测试。

I think a simple ` Reformat the code` command before any commit will just do the trick. For non-IDE-users, figure out your own way.

无法复现该问题，请确认数据移入过程正确。

我觉得这个本身就是一个bug

恢复速度问题在https://github.com/thulab/iotdb/pull/416中得到了一定的解决，请基于该分支重新测试。 内存溢出问题尚未能复现，建议先调大JVM内存。
