Little of both? :grin:
Primarily I am interested because of a grant [1] in which the Smithsonian Institution (where I work) is participating in a supporting role (partly because I
convinced us to). That work involves using Cassandra for distributed storage, and it will also involve a distributed
The jena-on-cassandra solution is quite simple. it is an implementation of
the graph layer so it doesn't do the joins directly but lets the higher
level do it. There are 4 copies of the data stored in different order
gspo, spog and 2 others that escape my mind at the moment but start with
"o" and
actually, looking at the code it is a datsset graph that the cassandra code
is built on.

I'd like to offer TDB2 as a contribution to Apache Jena.
It is by no means "finished" (is anything software ever finished?) but
it is sufficiently there to talk about and kick the tyres; I'll send
notes about the technical state of TDB2 separately in a moment.
* It adds project overhead. The
Compared to TDB1:
* No size limits on transactions
(my test is 100m BSBM triple upload into a live
Fuseki while still responding to queries)
* Transactional only (and currently no "autocommit").
* Better transaction control
* No queue of delayed updates
* No backlog problems.

I see no problem as we won't tell users to move to TDB2. There might be some
users who would be interested in testing it, and could help us to enhance the
code - though I agree things are rarely ever finished :)
