Heap access method specific configuration

Configuring the Heap access method is fairly simple. Beyond the general configuration required for any access method, you only need to decide how large you are willing to allow the database to become.

If you provide no configuration relative to the heap size, then the database will grow without bound. Whether this is desirable depends on how much disk space is available to your application.

You can limit the size of the on-disk database file by using the DB->set_heapsize() method. If the size specified on this method is reached, then further attempts to insert/update records will fail with a DB_HEAP_FULL error message.
