> If a user mistakenly inserts extremely large keys, the tablet server will eventually run out of memory just loading indexes.  This is almost certainly a mistake.  Add a constraint, by default, to new tables, which will limit the size of a key to a megabyte, for example, to catch these kinds of errors earlier.  If the user intends to use very large keys, they can always remove the constraint.
