I m uncertain as to the behaviour of the AllegroGraph triple store in regard to transactions. The tutorial talks about using two connections, but does not mention Jena models.
If I use Model s begin(), commit(), and abort() methods, do I still need to use two connections? How does a model interact with the connection s auto-commit setting?
The Jena tutorial doesn t have an example of transactions, but they are supported by using the Model methods: begin, commit, and abort.
You don t have to do anything manually with 2 connections. I ll work on clarifying the language in the tutorial.
The way it s implemented, when you call begin(), it calls setAutoCommit(false).
