Dear All, >From the document (https://jena.apache.org/documentation/tdb/optimizer.html), >it is said TDB optimizer has both static and dynamic optimizations. How can I get the estimated query time and row count instead of the actual time and row count after static/dynamic optimization? Another question is that I think "tdbquery -explain" gives the query plan after execution, but it also cannot provide the information I want.
What I want is to find the TDB optimizer's performance. Could anyone help? Thank you very much for your time. Best Regards, Wei
