Hash table reallocation (rehashing)

753334Feb 12 2010

Hello!
I use embedded Berkeley DB to store millions of small items (key ~ 16 byte, value ~ 16 byte). The exact number of items couldn't be known at the time of hash table allocation, so i push to set_h_nelem amount about 100 millions. After some period of time hash table becomes full and i need to rebuild (reallocate) it to avoid lacks in performance.

Does anyone know how to initiate manual hash table reallocation (to expand it) (C/C++ API is prefered)?
