> In Lucandra, I have a use case to pull all columns for a given row.
> I've noticed that for rows with large numbers of columns this takes much
> longer than I would think since row caching is enabled.
> After looking into this I see that the cached row is rebuilt and pruned even
> though I want all columns.
> This patch skips this use case and in my case has improved performance
> significantly.
> From ~400ms to ~50ms
