#include <db_cxx.h>

void DbInfo::set_bt_minkey(u_int32_t);


Set the minimum number of keys that will be stored on any single Btree page. This value is used to determine which keys will be stored on overflow pages, i.e. if a key or data item is larger than the pagesize divided by the bt_minkey value, it will be stored on overflow pages instead of in the page itself. The bt_minkey value specified must be at least 2; if bt_minkey is not explicitly set, a value of 2 is used.
