Get row has no batch mode in API documentation of a base.
On API, other fields have a "Batch Mode", but Get row doesn't have an example of batch mode.
In theory, List rows is the batch mode for Get row, but this is not shown how to use it to get rows by a set of ids, or a range of ids. The FIELD_ID returned by the Get fields method in the API does not have the FIELD_ID for the "row_id".

I'm pretty sure that there's a way to query by a set of row_ids in batch mode, but perhaps undocumented?
