Panagiotis Garefalakis updated ORC-619:
---------------------------------------
Parent: (was: ORC-577)
Issue Type: Task (was: Sub-task)
> Row-level filtering support for nested types
> --------------------------------------------
>
> Key: ORC-619
> URL: https://issues.apache.org/jira/browse/ORC-619
> Project: ORC
> Issue Type: Task
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis
> Priority: Major
>
> 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.
