Subject: [geometry] Some wild rtree ideas

Dear all,
I have put a question on stackoverflow http://stackoverflow.com/questions/27040161/boostgeometry-rtree-and-paging-lazy-load/27072352#27072352
Concerning boost geometry rtree and loading pages when needed. The answer is that iT is not supported yet.
http://stackoverflow.com/users/2574249/adam-wulkiewicz pointed me to this mailing list for help and ideas.
So hier I am.
Why page loading?
Some maps are to big to index as a whole and would-be beter to load parts only when needed.
Other ideas:
In combination with boost interproc maybe support for compressed mapped files? lz4 is quick enough when reading.
Custom page load mechanism that supports:
- retrieving data from different data sources ( database, zeromq,.... )
- dependcy checker to unload a page ( file, db query, time,....)
I realy have no idea if above suggestions are possible.
Thanks for your time,
Henry Roeland
