Subject Question about 'duplicate' columns
Date Tue, 06 Aug 2013 06:48:15 GMT
I've been thinking through some cases that I can see happening at some
point and thought I'd ask on the list to see if my understanding is correct.

Say a bunch of columns have been loaded 'a long time ago', i.e long enough
in the past that they have been compacted. My understanding is that if some
these columns get reloaded then they are likely to sit in additional
sstables until the larger sstable is called up for compaction, which might
be a while.

The case that springs to mind is filling small gaps in data by doing bulk
loads around the gap to make sure that the gap is filled.

Have I understood correctly ?
