[Yanel-dev] Data saving/writing locking

[Michael Wechner]

Hi

It happens that one wants to do data maintenance in the background, for 
example migrate from one repository to another
and hence all write/save access to data should be disabled.

Normally this is no problem with "editors", because one can tell them, 
but for example with regular end-users who fill out a form and an entry 
gets registered that doesn't work out.

I currently see two possibilities:

 1) Somehow introduce a switch to block all write/save access via an API

 2) Use a clustered environment where each cluster node can have it's 
own repository which get synchronized somehow
and hence one cluster node can be turned off and the corresponding 
repository can by synchronized after maintenance with the productive one 
and then the other way around

Any other ideas?

Thanks

Michi
