[erlang-questions] inconsistent results with fragmented table
Sat Jul 6 15:15:43 CEST 2013
Well, I've never written to this table before or after converting it to a fragmented table. When you say "this" can happen are you referring to the problem that Chandru said? That I've somehow ended up with records in the wrong fragment?

There seem to be a number of keys that don't show up in a read activity but, do show up when doing a table dump, a select, or using qlc to find records. As such, when this purge policy runs records are found that when I try to delete don't actually get deleted. It almost seems like read/delete are working off of one set while qlc is working off of another set.
