DOs cannot store values as large as KV
DOs cannot store values as large as KV. Limit of 128KiB per value vs 25MiB. DOs are also not replicated like KV is (KV has 2 central stores, one US one EU). And of course there are different throughput limits KV has unlimited throughput (other than write 1 per second to the same key). DOs limits as an exclusive key value store should be pretty high for both write and read (you can extend read far beyond write if you use the cache api as well). With DOs I would also make sure you are using multiple object ids to spread your keyspace across many objects increasing the overall throughput.
