Description

Normally the test finishes in 100ms. But it often costs 10s on my test machine.
Debug build is good.

I did brief debug, looks it's related to https://github.com/apache/arrow/pull/12302.
It stuck 10 seconds in destructing grpc::Server at code https://github.com/apache/arrow/blob/master/cpp/src/arrow/flight/server.cc#L863

To reproduce:

$ cmake -GNinja -DARROW_BUILD_TESTS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DARROW_FLIGHT=ON ..

$ ninja arrow-flight-test

$ relwithdebinfo/arrow-flight-test --gtest_filter="*DoPutLargeBatch*"
