Hi,
Do you mean haven a colum A then you want to extract A1 and A2 from A ?
like
Cloumn A value 123456,2019-08-07
A1 value is 123456
A2 value is 2019-08-07
If that's the case you can use df.select like this
df.select(split('A)(0) as "A1", split('A)(1) as "A2")
Good Luck

Hi,
I think that it should be possible to write a query on the streaming data
frame and then write the output of the query to S3 or any other sink layer.
