Hi,

I am reading the PR, but I think some design ideas need to be introduced ...

E.g., you change the data file structure from data/storage_group/*.files to
data/storage_group/{time range}/*.files..

Best,

Hi~
I'm working on this issue. In current storage group there is only one working processor for sequence data and one working processor for unsequence data. We will use a LRU map to hold working processor in different time range (timeRange -&gt; processor). Data in different time range will insert into different processor. Last frequent used processor will flush and close. If you have some ideas, please feel free to discuss with me.
