----------------------------------------

Indicate that there are more column qualifiers projected when you've truncated
the toString() based on the max number to display. Something simple like adding
a "..." to the string would be fine.
Increasing the default value to something like 20 or 30. That won't be an issue
memory-wise, but will handle more cases out of the box.

+1. Do you start the patch?

> When debugging, you often need to know which columns are projected into the
> Scan. The Operation.toString() silently truncates what you see to the first
> 5. Typically, if you truncate a value, you should end it with "..." so that
> the user knows there are actually more (instead of wasting time thinking
> they're not projecting everything that needs to be projected). Also, a limit
> of 5 is way to small of a default.
