Bandana efficiency for messaging

[ket.pjwstk]

Hi,

We're trying to use bandana as persistence storage for messaging in knowledge base system based on confluence. The system (when completed) will be avaiable for ~2k users and will be deployed on two mchines with load balancer. Our simple tests showed that bandana seems to fast. However we aren't sure if that is ther proper way deal with this task. We're also considering use of external DBs. Pleas let me know what do you think about it.

Note: there is no way estimate traffic before deployment.

Finally we've decied to extend confluence schema and use hibernate.

Well, I think there are quite a few people out there knowing issues with bandana too well. ;-) But after all, it is a matter of your use case and concrete design (how you store your data in Bandana).

You might want to check out this info:

Also, Atlassian is working on a new storage mechanism called/based-on Active Objects. This is a good intro, but there is much more on the web:

I see that you have no experience with such problems. Perhaps you could provide me some valubale (up to date) information about bandana architecture, i.e. confluence 3.5+
