Hi,
I and a fellow student of me are currently working on our diploma thesis
at the Dresden University of Technology (Germany), Chair for Database
Technology.
Our thesises deal about multi-version concurrency control and
cache-constrained based caching enhancements in relational databases.
-- How modular is the current transaction support integrated with the rest
of HSQLDB?
Hard to say how modular it is, but it is a simple scheme and is covered in a
few classes. Session keeps a list of rows deleted / inserted in memory and
when a commit is performed, the list is discarded. If a roll

replication. The HSQLDB side though must be improved with better transaction
isolation so that only committed transactions are replicated.
No direct work has been done on multi-version concurrency but some side
