> The Parquet Reader is a key use-case for Drill. This JIRA is an attempt to further improve the Parquet Reader performance as several users reported that Parquet parsing represents the lion share of the overall query execution. It tracks Flat Data types only as Nested DTs might involve functional and processing enhancements (e.g., a nested column can be seen as a Document; user might want to perform operations scoped at the document level that is no need to span all rows). Another JIRA will be created to handle the nested columns use-case.
