Huge amount of rentained messages and restarting

[skinkie]

The last action upon a restart is saving retained messages to /var/lib/flashmq/retained.db, would it be possible to do this in a different way, since it takes quite long to write it. In addition to it, it looks that flashmq needs a whopping 6GB of RAM, and my expectation is that this is mostly due to these retained messages, any chance to offload this?

For both issues, it would probably require integration with some kind of storage specific software, like something SQL based (Sqlite maybe). And then in such a way so that it's not a build-time requirement. Also, some kind of change tracking would have to be implemented.

I'll think about some solutions, perhaps intermediate ones as well.
