Fix Version/s: 0.7 beta 1
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
