Analyzing Neptune query execution using SPARQL explain
Amazon Neptune has added a SPARQL feature named explain. This feature is
a self-service tool for understanding the execution approach taken by the Neptune engine. You
invoke it by adding an explain
parameter to an HTTP call that submits a SPARQL
query.
The explain
feature provides information about the logical structure of query
execution plans. You can use this information to identify potential evaluation and execution
bottlenecks. You can then use query hints to improve
your query execution plans.
