rsique of forking commitUnitOfWork

Maarten Mostert
Hi,

This particular operation in my Gui greatly improves the overal speed and user expérience.


[self getGlorpSession commitUnitOfWork]  fork.


There are other areas where my UI could benefit from the above, but before generelising it use I wanted to check what the theoretical risk are.

PostgreSQL and SQLite are not multi-threaded like Oracle so there must be riss in doing this.

Regards,


Maarten MOSTERT

Are you using more than one connection to the DB? Or just multiple sessions?

In reply to this post by Maarten Mostert
SQLite is thread-safe if you use the default "serialized" mode, or compile it to be "multithred".

Dealing with I/O operations outside of the UI thread is always a good practice (in some cases like Android, it is enforced by UI scheduler).
I would add a few exception handling and callbacks, so you know how the commit ended, you can signal something or disable the UI from committing a new UOW in the same session. Altough I think the last case is handled by Glorp itself.

Regards!
