Muhammad Samir Khan updated SPARK-32531:
----------------------------------------
Component/s: Tests
> Add benchmarks for nested structs and arrays for different file formats
> -----------------------------------------------------------------------
>
> Key: SPARK-32531
> URL: https://issues.apache.org/jira/browse/SPARK-32531
> Project: Spark
> Issue Type: Test
> Components: SQL, Tests
> Affects Versions: 3.0.0
> Reporter: Muhammad Samir Khan
> Priority: Major
>
> We had found that Spark performance was slow as compared to PIG on some
> schemas in our pipelines. On investigation, it was found that Spark
> performance was slow for nested structs and array'd structs and these cases
> were not being profiled by the current benchmarks. I have some improvements
> for ORC (SPARK-32532) and Avro (SPARK-32533) file formats which improve the
> performance in these cases and will be putting up the PRs soon.
