------------------------------------------
Summary: Row-level filtering support for nested types
Key: ORC-619
URL: https://issues.apache.org/jira/browse/ORC-619
Project: ORC
Issue Type: Sub-task
Reporter: Panagiotis Garefalakis
Assignee: Panagiotis Garefalakis
In the current implementation we are propagating the selected array (using
filterContext) to the appropriate subtypes to allow row-level skipping.
This works for basic types such as Decimals and complex ones like inner structs
there is 1-1 mapping in the rows, however it more complex for nested types such
as Lists or Maps where the number of inner rows is different and thus needs
special handling.
