Dominique Pfister commented on JCR-1087:
----------------------------------------

Hi Martijn,

your patch looks good to me, so please go ahead and submit it. One nice thing that might be
required for people already owning a database journal: is there a way to easily detect whether
the LOCAL_REVISIONS table is missing and to tell the user to upgrade their schema?

Cheers
Dominique

> The revision table in which cluster nodes write their changes can potentially become
very large. If all cluster nodes are up to date to a certain revision number, then it seems
unnecessary to keep the revisions with a lower number.
