Hello Komяpa,
Thank you for your quick response,

So, if I correctly understand, we have:
- header,
- nodes/dense nodes,
- ways,
- relations.
Or do you mean something like this:
- header
- node/dense node/ways/relations in any order

:( So i need a btree for the node cache.
> 3. relations can be circular in any direction.
OK, so I need a second pass, the impact should not be too important on
execution time.
Kind regards
