Hi, When I refactor the filenode module, I found that Overflow module needs to be refactor first..
Overflow is similar with BufferWrite (sequence memtable), but it will generate OverflowFiles which is similar with TsFile but has some different properties... (for handling out-of-order data). I think the structure of Overflow should be similar with BufferWrite, and the OverflowWrite can be similar with TsFileWriter. That is what I want to refactor. I have created a JIRA https://issues.apache.org/jira/browse/IOTDB-41, and will submit some PRs to finish it.
