> Filesystem Plugin supports multiple type of file formats like
> 					* json
> 					* avro
> 					* 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
> *avro* and *parquet* and some of them are schema less like *json*.
> For schema based file formats, Drill should have capability to validate the query against file schema, before start executing the query.
