German Schiavon Matteo updated SPARK-30097:
-------------------------------------------
    Description: 
When using `writeStream` we always have to use `format("xxx")` in order to 
target the selected sink while in `readStream` you can use directly `.parquet`. 

Basically this is to add the support to the core writers for `writeStream`

Example:

`writeStream  .outputMode("append") .partitionBy("id") .parquet(path)`
