* If the wallet is created with HD support, it will have additional properties ``hdseed`` and ``hdchain`` that will be saved.
* ``version``, ``minversion``, ``witnesscachesize`` and ``bestblock`` properties are added. These are settings and state information: the ``bestblock`` property is a good example of the database being populated that is happening without any user interaction, but it will just update as the best block of the current chain changes.
At any time after the database is created new properties can be added as the wallet users do actions. For example, if the user creates a new sapling address with the rpc command ``getznewaddress()`` then new records with properties `sapzkey` and `sapzkeymeta` will be added to the database.

In zcashd, database changes do not happen immediately but they are flushed in its own thread by ``ThreadFlushWalletDB()`` function periodically to avoid overhead. The internal counter ``nWalletDBUpdated`` is increased each time a new write operation to the database is done, this is compared with the last flush in order to commit new stuff.
