Join in Mongo VS Hash Join
This experiments are made on the RDF integration system using GLAV mappings on BSBM 1M.
Methods Comparison
Total time
It is the total query answering time.
Rewriting time
The rewriting time is the time to build complete set of rewriting of the query according to mappings. It doesn't include optimizations.
Rewritings Processing Time
Rewritings processing is the part of query answering that concerns only rewriting building and rewriting optimization. It doesn't includes the query plan optimization and evaluation.
Query Plan Processing Time
Query plan processing time are the sum of query plan optimization and query plan evaluation. Since the two method returns minimal equivalent rewriting set, we expect that there is no time different between the two method at this step.
