public final class StardogRepositoryConnection
extends org.openrdf.repository.base.AbstractRepositoryConnection

Stardog-based implementation of a Sesame RepositoryConnection. Leaving autoCommit turned ON will yield sub-optimal performance with Stardog because of the overhead of pushing many single statement transactions. It is therefore highly recommended to use the begin() and commit()/rollback() methods to group operations into transactions unless absolutely required by your application

These connections keep a local cache of changes which are not pushed until they exceed a threshold, or an action, such as a query or a commit, requires them to be pushed to the server. This minimizes the overhead of calling add or remove in a tight loop with small payloads and then committing the entire thing, those updates would then be pushed in as few chunks as possible.

All queries created via this connection will implement the accessors for a query's maxQueryTime as no ops. The methods will work in that they will not throw an UnsupportedOperationException, however, they are not supported by Stardog. Timeouts cannot be controlled on a per-query basis, they are global server options.

Each of the specific prepare*Query methods, such as AbstractRepositoryConnection.prepareGraphQuery(org.openrdf.query.QueryLanguage, String) will parse the query during invocation, but it will not be type checked until execution time. For example, you can provide a valid ASK query to prepareGraphQuery and it will not fail that you're using a boolean query as a graph query until its executed. This is similar to how HTTPRepository handles this situation.
