Shu,

   IOTs are not, whether they are partitioned or not, any more than anything else, the answer. They are an answer to some special queries which are highly important to your application (and, possibly, reasons linked to ease of operation). If non-partitioned performs better, go for non-partitioned. The only problem I am aware of with partitioned IOTs is that you may have deadlocks with SELECTs if you are concurrently partitioning them (true in both 8.1.6 and 8.1.7).
