neptunedata_get_sparql_stream: Gets a stream for an RDF graph

Description

Gets a stream for an RDF graph.

See https://www.paws-r-sdk.com/docs/neptunedata_get_sparql_stream/ for full documentation.

Usage

neptunedata_get_sparql_stream(
  limit = NULL,
  iteratorType = NULL,
  commitNum = NULL,
  opNum = NULL,
  encoding = NULL
)

Arguments

limit

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

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

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

The operation sequence number within the specified commit to start reading from in the change-log stream data. The default is 1.

encoding

If set to TRUE, Neptune compresses the response using gzip encoding.
