Syntax

public abstract class BaseStardogConnector : BaseAsyncHttpConnector, IAsyncQueryableStorage, IAsyncStorageProvider, IAsyncTransactionalStorage, IConfigurationSerializable, IQueryableStorage, ITransactionalStorage, IReasoningQueryableStorage, IStorageProvider, IStorageCapabilities, IDisposable

Remarks

Has full support for Stardog Transactions, connection is in auto-commit mode by default i.e. all write operations (Delete/Save/Update) will create and use a dedicated transaction for their operation, if the operation fails the transaction will automatically be rolled back. You can manage Transactions using the Begin(), Commit() and Rollback() methods.

The connector maintains a single transaction which is shared across all threads since Stardog is currently provides only MRSW (Multiple Reader Single Writer) concurrency and does not permit multiple transactions to occur simultaneously.
