Review comment:
> v3 data table sent by server has metadata length as 0
That's impossible, since the `toBytes()` in V3 will always add a
`threadCpuTimeNs` KV pair to metadata, so for V3, metadata at least contains 1
KV pair. We can add a test: empty datatable (numRow = 0); datatable whoes
metadata only contains `threadCpuTimeNs` KV; datatable whoes metadata has
multiple KV pairs, etc
