Thomas Mueller commented on OAK-377:
------------------------------------
Hm, looking at the source code of the external sort, I see
Runtime.getRuntime().freeMemory() is used. I think it should be avoided, as the
returned value is kind of arbitrary (could be very low if called right before a
JVM full GC). Instead, I think a fixed memory chunk should be used, for example
8 MB (configurable). I guess it's not urgent, but something we could report.
The rest of the patch looks good, I will try to merge it and then do some more
review.

> Unused binaries in the data store need to be garbage collected.
> There is a partial implementation in oak-mk, however it is currently not run
> (not run automatically, and I think there is no way to run it manually).
> Also, we might want to investigate in faster garbage collection algorithms:
> young generation garbage collection, or garbage collection using reference
> counting (for example using an index of references to the data store).
