/**
 * tracker_sparql_connection_get:
 * @cancellable: a #GCancellable used to cancel the operation
 * @error: #GError for error reporting.
 *
 * This function is used to give the caller a connection to Tracker they can
 * use for future requests. The best backend available to connect to
 * Tracker is returned. These backends include direct-access (for read-only
 * queries) and D-Bus (for both read and write queries).
 *
 * You can use <link linkend="tracker-overview-environment-variables">
 * environment variables</link> to influence how backends are used. If
 * no environment variables are provided, both backends are loaded and
 * chosen based on their merits. If you try to force a backend for a query
 * which it won't support (i.e. an update for a read-only backend), you will
 * see critical warnings.
 *
 * When calling either tracker_sparql_connection_get(),
 * tracker_sparql_connection_get_direct() or the asynchronous variants of
 * these functions, a mutex is used to protect the loading of backends
 * against potential race conditions. For synchronous calls, this function
 * will always block if a previous connection get method has been called.
 * For asynchronous calls, this <emphasis>may</emphasis> block if another
 * synchronous or asynchronous call has been previously dispatched and is
 * still pending. We don't expect this to be a normal programming model when
 * using this API.
 *
 * All backends will call the D-Bus tracker-store API Wait() to make sure
 * the store and databases are in the right state before any user based
 * requests can proceed. There may be a small delay during this call if the
 * databases weren't shutdown cleanly and need to be checked on start up. If
 * the journal needs to be replayed in such an event, the delay may be
 * substantial while data is restored as best as possible.
 *
 * Returns: a new #TrackerSparqlConnection. Call g_object_unref() on the
 * object when no longer used.
