The question is : When does GreenDao update the sql database from the session cache?
Let say that I’m querying an existing entity out of the database and than change one of it properties(fields). The changes are performed without directing the sql database in anyway.
So – should I do update on the entity?
When does GreenDao flush it’s session cache into the database itself?
What you describe sounds like JPA/Hibernate session cache. greenDAO doesn’t have that. It is simpler. There are objects kept in memory and you always update them manually to the database.
