Berkeley DB

DB→set_bt_minkey

						#include <db.h>
						int
						DB→set_bt_minkey(DB *db, u_int32_t bt_minkey);
					

Description

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; that is, if a key or data item is larger than the underlying database page size divided by the bt_minkey value, it will be stored on overflow pages instead of within 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.

The DB→set_bt_minkey interface may only be used to configure Berkeley DB before the DB→open interface is called.

The DB→set_bt_minkey function returns a non-zero error value on failure and 0 on success.
