Newbie question - I have an inner bag of tuples that I'd like to convert
into an outer bag/relation and I'm struggling to figure out how
For example if I have
({(1,2),(3,4),(5,6)}
({(7,8),(9,10)}
I'd like it to become
(1,2)
(3,4)
(5,6)
(7,8)
(9,10)
The motivation behind that is a Cassandra field that contains a packed,
variable-length data structure, a bit like a CSV string encoding multiple
rows of data
I can convert the raw char array into an inner bag of tuples but I need to
'explode' it to work properly with it
I'm open to "don't do that, here's why it's a dumb idea", but it feels like
I'm missing an operator that could be used to implement this. I have a
partially-working solution using streaming, but the presence of new lines in
the chararray makes that approach tough. Any advice much appreciated.
cheers,
Pete
