What changes were proposed in this pull request?
This PR aims to extend the existing benchmarks to save JDK9+ result separately.
All
coremodule benchmark test results are added. I'll run the other test suites in another PR.After regenerating all results, we will check JDK11 performance regressions.
Why are the changes needed?
From Apache Spark 3.0, we support both JDK8 and JDK11. We need to have a way to find the performance regression.
Does this PR introduce any user-facing change?
No.
How was this patch tested?
Manually run the benchmark.
