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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
