> In theory, we shouldn't hit a lease timeout for aggregate queries, because we chunk up the scan on the client side to manageable chunks. However, I believe [~mujtabachohan] has seen this occurring. Another curious issue is that unless we open the scanner when the iterator is created, aggregate scans take a perf hit which I don't completely understand. Another thing that [~lhofhansl] noticed was that running the scan on the region server during the post scanner open hook could be problematic. We might need to run the scan instead on the first next() call we get from the client instead.
