Issues covered include a mostly conservative but also paged garbage collector, the difficulty of clearing out data structures that are retainted as an optimization but that might hold on to large amounts of heap (and how that happens in C++, too) and how large intercollected and theoretically uprooted "clouds of heap debris" interact with stale pointers out of same. The most delicious pieces center around pointer staleness out of the saved (on-disk, but read-write mapped) part of the heap, which is not garba ge collected, into anonymous memory backed heap and how you can create rootless but uncollected and "untraceable" object circles. Untraceabl e until you hack up the GC to help you.

These data structures are allocated fr om a memory area called the “heap”. However, there are times when heap allocation is inadequate to satisfy the needs of the application. For example, sometimes data structures need to be persistent or shareable amongst separate processes. In these cases, alternatives to using the heap must be considered.\n\nIn this talk we will explore the motivati ons for out-of-heap data structures. We will discuss some of the out-o f-heap data structures that we’ve created in the course of developing our database product, such as lists, hash tables, and arrays. We will describe the tools and mechanisms that we used to implement them, incl uding memory-mapped files, foreign structs, aligned pointers and direc t memory accesses. Finally we will discuss the downsides of out-of-hea p data structures and the constant struggle between abstractions and p erformance.
