-------------------------------
Component/s: ORC
> Support predicate pushdown for complex data types in ORCFile
> ------------------------------------------------------------
>
> Key: HIVE-7214
> URL: https://issues.apache.org/jira/browse/HIVE-7214
> Project: Hive
> Issue Type: Improvement
> Components: File Formats, ORC
> Reporter: Rohini Palaniswamy
> Labels: ORC
>
> Currently ORCFile does not support predicate pushdown for complex datatypes
> like map, array and struct while Parquet does. Came across this during
> discussion of PIG-3760. Our users have a lot of map and struct (tuple in pig)
> columns and most of the filter conditions are on them. Would be great to have
> support added for them in ORC
