> Index maintenance is not correct when rows arrive out of order (see PHOENIX-4052). In particular, out of order deletes end up with a spurious Put in the index. Rather than corrupt the secondary index, we can instead just ignore out-of-order mutations. The only downside is that point-in-time queries against an index will not work correctly.
