---------------------------------
Summary: Expose repetition & definition level from ColumnIO
Key: PARQUET-2050
URL: https://issues.apache.org/jira/browse/PARQUET-2050
Project: Parquet
Issue Type: Improvement
Reporter: Chao Sun
Assignee: Chao Sun
{{ColumnIO}} is pretty useful for obtaining repetition and definition level
info, for constructing nested records (the {{ColumnDescriptor}} only expose the
info for leave nodes). However, currently {{getDefinitionLevel}} and
{{getRepetitionLevel}} are both package-private and other applications depend
on Parquet have to find workaround for this (e.g., [ColumnIOUtil used by
Presto|https://github.com/prestodb/presto-hive-apache/blob/master/src/main/java/org/apache/parquet/io/ColumnIOUtil.java]).
