When organizing available free storage for re-use, we will probably have
a choice whether to favor using space in (mostly-) empty blocks, or in
mostly-full blocks. Empty and mostly-empty blocks are quicker -- you
can put lots of rows in them before they fill up and you have to choose
another. Preferring mostly-full blocks improves active-storage and
cache density because a table tends to occupy fewer total blocks.
Does anybody know of papers that analyze the tradeoffs involved?
