Values.GetPropertygraphStreamInputSourceGets a stream for a property 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. GetPropertygraphStream lets you collect these change-log entries for a property 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. 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 enables one of the following IAM actions, depending on the query: Note that you can restrict property-graph queries using the following IAM context keys: neptune-db:QueryLanguage:Gremlin neptune-db:QueryLanguage:OpenCypher See Condition keys available in Neptune IAM data-access policy statements).
type nonrec t = {limit : GetPropertygraphStreamInputLimitLong.t option;Specifies the maximum number of records to return. There is also a size limit of 10 MB on the response that can't be modified and that takes precedence over the number of records specified in the limit parameter. The response does include a threshold-breaching record if the 10 MB limit was reached. The range for limit is 1 to 100,000, with a default of 10.
*)iteratorType : IteratorType.t option;Can be one of: AT_SEQUENCE_NUMBER - Indicates that reading should start from the event sequence number specified jointly by the commitNum and opNum parameters. AFTER_SEQUENCE_NUMBER - Indicates that reading should start right after the event sequence number specified jointly by the commitNum and opNum parameters. TRIM_HORIZON - Indicates that reading should start at the last untrimmed record in the system, which is the oldest unexpired (not yet deleted) record in the change-log stream. LATEST - Indicates that reading should start at the most recent record in the system, which is the latest unexpired (not yet deleted) record in the change-log stream.
*)commitNum : Long.t option;The commit number of the starting record to read from the change-log stream. This parameter is required when iteratorType isAT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER, and ignored when iteratorType is TRIM_HORIZON or LATEST.
*)opNum : Long.t option;The operation sequence number within the specified commit to start reading from in the change-log stream data. The default is 1.
*)encoding : Encoding.t option;If set to TRUE, Neptune compresses the response using gzip encoding.
