Dear OpenLDAP-Community,


is it possible to compute a rough estimate of the number of elements between
two given keys for an LMDB database?

Currently, I scan the first 1000 keys and extrapolate the count based on the
average distance of the keys.

Maybe it is also possible to use some information about the common b-tree
pages that are shared by both keys?

We need this functionality for query optimization within RDF4J.



Thank you for your support and best regards,

Ken Wenzel
