The update from version 4.0.0-rc01 to 4.0.0-rc02 introduces two key performance enhancements:

  • Resolved the query OOM issue caused by compaction. Previously, Q5 failed due to contention with the compaction process.
  • Reduced the default bucket size to enhance parallelization efficiency.

The current test result was generated using ./main.sh and the docker image of version 4.0.0-rc02. For fairness, you are encouraged to rerun the tests to validate the results.

@murphyatwork In my local measurements, Q5 in the biggest run still failed (no output).

For transparency, I dumped the output of the run to #94 if you like to check.

May i ask the spec of the EBS in your testing env? I feel like it's still the compaction issue. I'm using a EBS with 10K IOPS & 500MB/s bandwidth to run the test.
