So my first question: Does mdb have limitations like bdb it have aka BDB_IDL_LOGN?
Yes. back-mdb is ~60% the same code as back-bdb/hdb, its indexing functions are basically identical.
However, I never got mdb to work successfully by modifying these values.
Does this mean, it's not possible at moment to get running the mdb with BDB_IDL_LOGN = 2^17?
I can guarantee that would never work, as the variable with MDB is MDB_IDL_LOGN. I don't recall exactly the issues I hit when changing it to 17 from 16. Also, MDB has changed substantially since I did that testing. ;) I was ok with not modifying it given the read speed improvements in mdb vs bdb.
