If you have a wide table and want to optimize performance you would do better to increase the page size.

Hi,


Morning!


"Put small and frequently used columns early in the table to minimize
the need to follow the overflow chain."

Now, that's interesting! And I'm wondering whether there is a big
performance hit for a simple

        SELECT binarydata FROM entries WHERE somehash = 27817298;



That is interesting!

I guess this would only apply if the indexed columns in a single row are
larger than the page size of the btree table.

I don't know for sure, but I would bet the overhead of creating an index
to join the two tables would be much higher than the overhead of loading
an overflow page.

It's probably worth looking into
