Hi @Dandandan, I tried profiling the execution with the following command: ```bash CARGO_PROFILE_RELEASE_DEBUG=true cargo flamegraph -o q8.svg -- -f q8.sql ``` > Note: I have an `x` directory generated by falsa with > ```bash > falsa groupby --path-prefix=./x --size MEDIUM --data-format PARQUET > ``` From the flamegraph, I see that the `concat_batches` function you mentioned only takes < 5% of the total time. Since I'm not very familiar with this type of performance optimization, I'm unsure whether this is the primary issue. I may need more time to investigate further. -- This is an automated message from the Apache Git Service.
