> Filesystem Plugin supports multiple type of file formats like

> * text (csv|psv|tsv)
> * parquet
> and can support any type of file formats.
> Among these file formats, some of the file formats are schema based like

> For schema based file formats, Drill should have capability to validate the query against file schema, before start executing the query.
