Class BigdataSailRemoteRepositoryConnection

java.lang.Object

com.bigdata.rdf.sail.remote.BigdataSailRemoteRepositoryConnection

All Implemented Interfaces:

org.openrdf.repository.RepositoryConnection

public class BigdataSailRemoteRepositoryConnection
extends Object
implements org.openrdf.repository.RepositoryConnection

An implementation of Sesame's RepositoryConnection interface that wraps a bigdata RemoteRepository. This provides SAIL API based client access to a bigdata remote NanoSparqlServer.

Transactions

The database supports read/write transactions since 1.5.2. Transaction manager is at the database layer, not the Repository or RepositoryConnection. Therefore a namespace DOES NOT need to be configured for isolatable indices in order to create and manipulate transactions, but it DOES need to be configured with isolatable indices in order for you to WRITE on the namespace using a transaction.

See Also:

RemoteTransactionManager, BigdataSail.Options.ISOLATABLE_INDICES, Support read/write transactions in the REST API, BigdataSailRemoteRepositoryConnection should implement interface methods FIXME (***) #698 Fix all the Query objects (TupleQuery, GraphQuery, BooleanQuery) to support the various possible operations on them, such as setting a binding.

isAutoCommit

@Deprecated
public boolean isAutoCommit()
                     throws org.openrdf.repository.RepositoryException

Deprecated.

Note: This is deprecated in openrdf since 2.7.x. The semantics are that a connection without an active transaction is in "auto-commit" mode.

Specified by:

isAutoCommit in interface org.openrdf.repository.RepositoryConnection

Throws:

org.openrdf.repository.RepositoryException

setAutoCommit

@Deprecated
public void setAutoCommit(boolean autoCommit)
                   throws org.openrdf.repository.RepositoryException

Deprecated.

Note: This is deprecated in openrdf since 2.7.x. The semantics are that a connection without an active transaction is in "auto-commit" mode. If there is an open transaction and auto-commit is disabled, the open transaction is committed. This is per the openrdf API.

Specified by:

setAutoCommit in interface org.openrdf.repository.RepositoryConnection

beginReadOnly

public void beginReadOnly()
                   throws org.openrdf.repository.RepositoryException

Begin a read-only transaction. Since all read operations have snapshot isolation, this is only necessary when multiple read operations need to read on the same commit point.

Throws:

org.openrdf.repository.RepositoryException

beginReadOnly

public void beginReadOnly(long timestamp)
                   throws org.openrdf.repository.RepositoryException

Begin a read-only transaction that reads against the most recent committed state whose commit timestamp is less than or equal to timestamp.

Note: Since all read operations have snapshot isolation, this is only necessary when multiple read operations need to read on the same commit point. TODO While the ability to do read-only operations against a specified timestamp without a transaction exists, it is not exposed by this interface nor can be accomplished using RemoteRepository since that interface also lacks mechanisms (e.g., prepareTupleQuery(String:query,long:commitTime)) to express this request.
