Investigate segfault when trying to use kRange in sampling CE bm

XMLWordPrintableJSON

    • Type: Bug
    • Resolution: Fixed
    • Priority: Major - P3
    • 8.3.0-rc0
    • Affects Version/s: None
    • Component/s: None
    • None
    • Query Optimization
    • Fully Compatible
    • ALL
    • Hide

      To repro, change the following line of code for `queryConfig1` to be `kRange`.

      Then run the `BM_RunCardinalityEstimationOnSample` Benchmark and there will be segfault with the stacktrace attached to the bottom of this ticket. I added log lines inside the `createQueryMatchExpressionOnMultipleFields()` function and noted that it failed during the first iteration of the inner loop here.

      When running sampling ce benchmarks with the `kRange` type specified for a query, we run into a segfault.
