we can calculate this, right?

I think only the underlying driver can give us the accurate bytes read count.
In this code we're only able to see the Java objects returned by the driver, that's not the same as bytes read over the wire.
Even if we want to use the Java objects size as a proxy for bytes read, we don't have a nice way to get the size of the object returned by io.trino.plugin.jdbc.ObjectReadFunction#readObject. I expect that this number would turn out to be similar to processed input bytes that is tracked by the engine anyway.

Can we repot size of the pages created? This is a rough estimate on the size of the data since we are not using dictionary encoding here. Most of the databases are using binary framing which is similiar to our in memory structures.

[raunaqmorarka]

Processed input bytes is already tracking size of pages and that is done by the engine independently of the connector, this field is about the connector reporting physical input bytes

Sure, ship it!
