Dorjee Tsering updated SPARK-54838:
-----------------------------------
Issue Type: New Feature (was: Bug)
> Optimize spark partition size
> -----------------------------
>
> Key: SPARK-54838
> URL: https://issues.apache.org/jira/browse/SPARK-54838
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 4.2.0
> Reporter: Dorjee Tsering
> Priority: Minor
>
> I am proposing to add a new function in Dataset class to fix small file
> problem. We have noticed that if the source data our spark job reads have
> many small files (KB size), it creates lot of partitions. This PR adds a new
> function named optimizePartition which when used creates partitions of size
> 128MB if no desired partition's size passed. You can pass your own desired
> partition size.
