Answer 1

If speed is the most important when retrieving the rows then make a new table and make it dedicated to holding the indices of your array. Use the data type of integer and have each row represent an index of the array. You'll have to create another numeric column which binds these together so you can re-assemble the array with an SQL query.

This way you help MySQL help you speed up access. If you only want certain parts of the array, you just change the range in the SQL query and you can reassemble the array however you want.
