-----------------------------------
Summary: Support Int8 and Int16 as basic type
Key: PARQUET-2133
URL: https://issues.apache.org/jira/browse/PARQUET-2133
Project: Parquet
Issue Type: Improvement
Components: parquet-format
Reporter: Jackey Lee
Int8 and Int16 are not supported as basic in previos version. Using 4 bytes to
store int8 seems not a good idea, which means requiring more storage and read
and write very slow. Besides, it is not friendly with regular computing format,
such as velox, arrow, vector and so on.
With Int8 and Int16 supported, we can get less storage and better performance
on reading and writing. As for forward compatible, we can use version in
FileMetaData to choose how to read parquet data.
