The queryId
SPARQL Query Hint
Use this query hint to assign your own queryId value to a SPARQL query.
Example:
PREFIX hint: <http://aws.amazon.com/neptune/vocab/v01/QueryHints#> SELECT * WHERE { hint:Query hint:queryId "4d5c4fae-aa30-41cf-9e1f-91e6b7dd6f47" {?s ?p ?o}}
The value you assign must be unique across all queries in the Neptune DB.
