LinGeLin commented on ARROW-17740:
----------------------------------
I'm giving up on Acero。I have also tested DuckDB and DuckDB also performs
poorly when reading many columns. Any other suggestions? Otherwise, I'm gonna
have to tank.
> [c++][compute]Is there any other way to use Join besides Acero？

> Acero performs poorly, and coredump occurs frequently！
>
> In the scenario I'm working on, I'll read one Parquet file and then several
> other Parquet files. These files will have the same column name (UUID). I
> need to join (by UUID), project (remove UUID), and filter (some custom
> filtering) the results of the two reads. I found that Acero could only be
> used to do join, but when I tested it, Acero performance was very poor and
> very unstable, coredump often happened. Is there another way? Or just another
> way to do a join!

> tensorflow ==2.6.2
> you can build tfio as follows:
> ./configure.sh
> bazel build -s- -verbose_failures $BAZEL_OPTIMIZATION //tensorflow_io/...
> //tensorflow_io_gcs_filesystem/... --compilation_mode=opt --copt=-msse4.2
> --copt=-mfma --copt=-mavx2
> python setup.py bdist_wheel --data bazel-bin
> pip install dist/tensorflow_io-0.21.0-cp38-cp38-linux_x86_64.whl
> --force-reinstall --no-deps
>
> run v4test.py to test the dataset
>
> Data.zip contains several parquet files, which are stored on S3 in my
> scenario.
> I have copied some of the code into test.cpp and can only see the general
> flow, not compiled
