How to stop generating empty Parquet files when there is no data.

[ShahBinoy]

Hi @flarco ,

I have data being fetched from MySQL database using a custom query in Replication.

Lot of times there is no data coming back for a certain query, in such scenario, Sling creates empty parquet file, this throws off the collective scanning of data.

Is there a way to not create parquet file if the row count returned is 0 ?

Ah ok, will fix that in next release, thanks.
