Hmm, what about to create fragmented tables in Mnesia related to your
database, write to it {Key, Record} information about changed records,
Record could be direct binary from C struct:

1. Mnesia distribute this tables.

2. Update on slave node.
2.1 Your slave node reads its local replica and updates database table.
2.3 Because table is fragmented it can safely delete record from
Mnesia.
