Daniel Weeks commented on PARQUET-409:
--------------------------------------
I definitely think it's worth exposing as a configurable property. However, I
haven't seen an issue where these checks are producing bad row group sizes.
I have seen some outlier datasets that have rows in excess of 10MB, but only a
few records per file. With that kind of size, you could get disproportionately
sized row groups given enough records.
> InternalParquetRecordWriter doesn't use min/max row counts

> Key: PARQUET-409
> URL: https://issues.apache.org/jira/browse/PARQUET-409
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Affects Versions: 1.8.1
> Reporter: Ryan Blue
> Fix For: 1.9.0
>
>
> PARQUET-99 added settings to control the min and max number of rows between
> size checks when flushing pages, and a setting to control whether to always
> use a static size (the min). The [InternalParquetRecordWriter has similar
> checks|https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/InternalParquetRecordWriter.java#L143]
> that don't use those settings. We should determine if it should update it to
> use those settings or similar.
