-------------------------------------
How to reproduce this issue?
> High GC and memory footprint after switch to ZSTD
> -------------------------------------------------
>
> Key: SPARK-38703
> URL: https://issues.apache.org/jira/browse/SPARK-38703
> Project: Spark
> Issue Type: Question
> Components: Input/Output
> Affects Versions: 3.1.2
> Reporter: Michael Taranov
> Priority: Major
>
> Hi All,
> We started to switch our Spark pipelines to read parquet with ZSTD
> compression.
> After the switch we see that memory footprint is much larger than previously
> with SNAPPY.
> Additionally GC stats of the jobs are much higher comparing to SNAPPY with
> the same workload as previously.
> Is there any configurations that may be relevant to read path, that may help
> in such cases ?
