Hi LingZhe,
Good idea, A small question, how to define the latest files? 10 minutes, 1 hour, or the last day? I think this parameter is best left to the user to configure.

We have this usage scenario where we want to read and take out data within an hour in the quickest possible time, beyond which the data becomes worthless.

When user write too fast, the compaction can just merge useless data. In this condition, the compaction can just cause bad effect. So we have to develop a compaction strategy that can merge latest file as soon as possible, and use it as default startegy. I will realize it[1] later. What do you think of it?
