Howard,

If it doesnt swap, what will it do in case of db size is larger than actual RAM? also how does it manage the physical RAM? meaning what % system RAM does it use? is it configurable ? will it case any OOM issues? i am trying to migrate from hdb to mdb in prod so trying to understand mdb. How does it work in case of reads and writes?

Thanks,

Ram

Ok, but are there any casses where DB size can grow bigger then RAM and
what will happen in that case?

Same thing that happens in any such case.. it'll start swapping.

LMDB never uses swap.
