const (
	StrVal = ValType(iota)
	IntVal
	FloatVal

Per the MySQL docs, http://dev.mysql.com/doc/refman/5.7/en/replace.html Replace is the counterpart to `INSERT IGNORE`, and works exactly like a normal INSERT except if the row exists. In that case it first deletes the row and re-inserts with new values. For that reason we keep it as an Insert struct. Replaces are currently disallowed in sharded schemas because of the implications the deletion part may have on vindexes.
