> ORC split generation does not have clearly defined strategies for different scenarios
(many small orc files, few small orc files, many large files etc.). Few strategies like storing
the file footer in orc split, making entire file as a orc split already exists. This JIRA
to make the split generation simpler, support different strategies for various use cases (BI,
ETL, ACID etc.) and to lay the foundation for HIVE-7428.
