Duo Zhang commented on HBASE-15454:
-----------------------------------
So you mean if there is a 'max age' config then we will do the archive work?
Alright, seems OK.
And for the concat issue, sorry maybe the word is not accurate. I mean that, if
we have different window implementation, and switch the implementation when
crossing the 'max age' point, then we need to see how we can switch smoothly
without leaving a hole there or overlapping.
And for archive, I prefer to write all data between the window into this file,
so the input files may contain files in other window because we only consider
maxTimestamp or minTimestamp when assign files to window.
Have a nice trip!

> Sometimes the old data is rarely touched but we can not remove it. So archive
> it to several big files(by year or something) and use EC to reduce the
> redundancy.
