Apache Spark reassigned SPARK-25356:
------------------------------------
Assignee: Apache Spark
> Add Parquet block size (row group size) option to SparkSQL configuration
> ---------------------------------------------------------------------------
>
> Key: SPARK-25356
> URL: https://issues.apache.org/jira/browse/SPARK-25356
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: liuxian
> Assignee: Apache Spark
> Priority: Minor
>
> I think we should configure the Parquet buffer size when using Parquet format.
> Because for HDFS, `dfs.block.size` is configurable, sometimes we hope the
> block size of parquet to be consistent with it.
> And whether this parameter `spark.sql.files.maxPartitionBytes` is best
> consistent with the Parquet block size when using Parquet format?
