Abstract
Official abstract text for this publication.
As disclosed herein a method, executed by a computer, for enabling a SPARQL explain tool that provides query execution statistics via an explain plan includes initiating a database query comprising a SPARQL query pattern, optimizing the database query according to query semantics and database metadata to produce an optimized query, and generating an explain plan for the optimized query. The explain plan may include a sequence of operations and an execution time, an input, and an output for each operation of the sequence of operations. A computer system, and a computer program product corresponding to the method are also disclosed herein.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method, executed by a computer, for enabling a SPARQL explain tool which provides query execution statistics via an explain plan, the method comprising: initiating a database query comprising a SPARQL query pattern; optimizing the database query according to query semantics and database metadata to produce an optimized query; and generating an explain plan from the optimized query, the explain plan comprising a sequence of operations and an execution time, an input, and an output for each operation of the sequence of operations. 2 . The method of claim 1 , wherein at least a portion of the explain plan is presented to a user. 3 . The method of claim 1 , wherein the explain plan further comprises a row cardinality for each operation of the sequence of operations. 4 . The method of claim 1 , wherein the explain plan further comprises an index indicator for each operation of the sequence of operations. 5 . The method of claim 1 , wherein the explain plan comprises one or more known bindings and one or more produced variables for a step that correspond to the SPARQL query pattern. 6 . The method of claim 1 , wherein the explain plan further comprises a distinct keyword indicator for each operation of the sequence of operations. 7 . The method of claim 1 , wherein the explain plan comprises query execution statistics.
