#include <db_cxx.h> int Db::set_bt_minkey(u_int32_t bt_minkey);
Set the minimum number of key/data pairs intended to be stored on any single Btree leaf page.
This value is used to determine if key or data items will be stored on overflow pages instead of Btree leaf pages. For more information on the specific algorithm used, see Minimum keys per page. The bt_minkey value specified must be at least 2; if bt_minkey is not explicitly set, a value of 2 is used.
The Db::set_bt_minkey()
method configures a database, not only
operations performed using the specified Db
handle.
The Db::set_bt_minkey()
method may not be called after the
Db::open()
method is called. If
the database already exists when
Db::open()
is called, the information specified to Db::set_bt_minkey()
will be ignored.
The Db::set_bt_minkey()
method either returns a non-zero error value or throws an
exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
The Db::set_bt_minkey()
method may fail and throw a DbException
exception, encapsulating one of the following non-zero errors, or return one
of the following non-zero errors:
If the method was called after Db::open() was called; or if an invalid flag value or parameter was specified.
