>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.
