@User Pinot works with its own internal segment format, so data will be converted from other formats. We currently don't have support for ORC/Parquet.

@Sunitha Could pinot provide such interface to make it extensible to allow user to develop different kind of interfaces of different underlined storage format, just like what druid extension(http://druid.io/docs/latest/development/extensions.html) do?

Pinot does have interfaces that one can use to implement different storage formats, check the readers and writers interfaces in pinot core
