TerminusDB represents the data using succinct data structures which reduces the required memory substantially over many other representations. Each branch needs to be capable of being loaded into memory completely - but individual revisions are loaded separately.

Diffs can be constructed between two objects, or you can get sets of diffs of objects between commits automatically. You can manually construct diffs and use them to patch branches.

We don't have a conversion tool from SQL database tables, but it's something on my list.
