`Transient.Store` is a `dbadapter.Store` with a `dbm.NewMemDB()`. All `KVStore` methods are reused. When `Store.Commit()` is called, a new `dbadapter.Store` is assigned, discarding previous reference and making it garbage collected.
`Transient.Store` is a `dbadapter.Store` with a `coretesting.NewMemDB()`. All `KVStore` methods are reused. When `Store.Commit()` is called, a new `dbadapter.Store` is assigned, discarding previous reference and making it garbage collected.
This type of store is useful to persist information that is only relevant per-block. One example would be to store parameter changes (i.e. a bool set to `true` if a parameter changed in a block).
