Gets a stream for an RDF graph.
With the Neptune Streams feature, you can generate a complete sequence of change-log
entries that record every change made to your graph data as it happens. GetSparqlStream
lets you collect these change-log entries for an RDF graph.
The Neptune streams feature needs to be enabled on your Neptune DBcluster. To enable
streams, set the neptune_streams
DB cluster parameter to 1.
See Capturing graph changes in real time using Neptune streams.
When invoking this operation in a Neptune cluster that has IAM authentication enabled, the IAM user or role making the request must have a policy attached that allows the neptune-db:GetStreamRecords IAM action in that cluster.
Note that the neptune-db:QueryLanguage:Sparql IAM condition key can be used in the policy document to restrict the use of SPARQL queries (see Condition keys available in Neptune IAM data-access policy statements).
For .NET Core this operation is only available in asynchronous form. Please refer to GetSparqlStreamAsync.
