Re: Contribution of TDB2

+1 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 :) CheersBruno From: Andy Seaborne To:

[jira] [Commented] (JENA-1389) Return `this` rather than `void` from Dataset

TDB2 features

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.

Contribution of TDB2

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

Re: Jena over Cassandra?

actually, looking at the code it is a datsset graph that the cassandra code is built on. On Mon, Sep 4, 2017 at 5:17 PM, Claude Warren wrote: > 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

Re: Jena over Cassandra?

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
