I personally just added a 'profiling' profile that inherits release-nonlto and set debug to true. |

Which issue does this PR close?
Rationale for this change
release-nonltobuild produces binaries with performance close to--releasebuild, but compiles faster. This compilation profile is used for easier development and benchmarking.Now it by default strips the debug symbols, as a consequence, If a flamegraph is collected using this
release-nonltobuild, useful function names will not displayed.Reproducer:
sudo cargo flamegraph --profile release-nonlto --bin dfbench -- sort-tpch -p /Users/yongting/Code/datafusion/benchmarks/data/tpch_sf10 -q 3The generated flamegraph will look like:
If we keep the symbol names, the flamegraph will be generated with function names in the call stack.
