There are cases where people need datafusion but not a SQL parser. For
example, people building a composable query engine for graph or other data
modality may not choose SQL as the DSL. Decoupling them seems to be a good
idea.

Hi the arrow community,

Trying to get some attention to this performance question.
Do you have some large cypher queries as test cases? Those from LDBC are
relatively small.

I asked a question here about vectorized processing.

Any idea? I am also open to the approaches like Intel MKL, xsimd, clang and
so on.

After running

I am trying to create a debug build for arrow and gandiva to be used in
c++, possibly in python as well.
Using the following step
cd $ARROW_SOURCE_DIR
cd cpp
rm -rf build
mkdir build
cd build/
cmake .. \
-DBUILD_WARNING_LEVEL=PRODUCTION \
--preset ninja-debug-gandiva
cmake --build . -j 14
