>heap dump analysed with MAT
Thank you.
Even though the preferred solution is to buffer data rather than fetch all
the rows to the heap, it looks like Tuple costs 30% or so of the heap :-/
Just in case, the columns are "number of objects", "shallow heap" (==heap
consumption by the object itself), "retained heap" (==heap consumption of
the object+all its references).
We might want to revise the addition of Tuple.
