Description

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
