Review comment:
Yeah, we missed this in the other patch.

Review comment:
We can get the read size already from the `Records` object. The code
must have been changed at some point to use this. It looks like
`adjustedMaxBytes` is still sent through in the call to `Partition.readRecords`.

Review comment:
Do we get the labels from the default `toString`? In the past, I thought
it would only show the values.
