> The problem is that the different stores have different transient space characteristics. for example the MongoMK is very slow when handling large saves.
> suggest to expose a repository descriptor that can be used to estimate the preferred transient space, for example when importing content.
> so either a boolean like: 
>   {{option.infinite.transientspace}}
> or a number like:
>   {{option.transientspace.preferred.size}}
> the later would denote the average number of modified node states that should be put in the transient space before the persistence starts to degrade.
