-------------------------------
Summary: 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
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?
