I mentioned some of this in another thread. We have a readonly database which get bulk loaded using HFiles. We want to keep only two versions/generations of data. Since the size of data is massive we need to delete the older generation.
Since we write one single HBase for each region for each CF for each generation, could we just yank the older files using a separate standalone process? (sounds a little scary) If not, could we write a custom compactor? what's involved (some pointers please)? thanks Jeff
