Yes, you see they are different. No other operations between them. The data set is 100m used in milvus_bootcamp.

SEARCH_PARAM=64. The index is IVF_SQ8. The dataset is 100m, and I follow the steps to create the index: in https://github.com/milvus-io/bootcamp/blob/master/benchmark_test/lab2_sift1b_100m.md I have created a Java program to reproduce this issue....

I have uploaded my Java program to: https://github.com/ministat/milvus-unstable-results. Please check whether you can reproduce this issue.

@Mats-SX Thanks for your reply. Unfortunately, I got exception when I run the cyper you suggested. It looks like the pattern is unsupported. ``` Exception in thread "main" org.opencypher.okapi.impl.exception.NotImplementedException: Support...

The exception changed, but unfortunately, it still failed for something not implemented. ``` 23/09/27 10:25:12 WARN SparkSession$Builder: Using an existing SparkSession; some configuration may not take effect. Exception in thread...

@Mats-SX Do you have any document introducing the design and implementation? I'd like to evaluate the effort to support this feature. That will be great if you or your colleagues...

Yes. It looks quite close to be working. However, there is an exception. Can I ignore this? ``` Exception in thread "main" org.opencypher.okapi.impl.exception.IllegalArgumentException: Expected: Header does not contain a column...

Thanks for your patient response. The following cypher does not throw exception nor give the expected result. ``` MATCH (start:Application {alias: "r1shsummaryv2"})-[r:DependsOn*..2]->(end:Application {alias: "r1appmetasvccont"}) RETURN r ╔══════╤══════╤══════════════════════════════════════════════════════════════════════════════════════════╗ ║ r(1) │...

It is not easy to reproduce this thread safe issue in a UT, anyway let me try.

The UT cannot reproduce this issue. Only the production env can see it. If the UT is a must, I suggest abondoning this PR.
