Andy Seaborne updated JENA-486:
-------------------------------
Description:
TDB transactions (which are DatasetGraphs built in DatasetBuilderTxn) have
limited calability.
BlockMgrJournal, used for modified data in indexes is an in-memory structure.
The transactional NodeTableTrans keeps the new objects on disk but uses
IndexMap for some access structures.
