I have a dataset written in Avro format,
I read it using
b = load 'myfile' using AvroStorage();
describe b;
it shows the following schema: it seems that at the root level, there are
only 2 fields: key and value, the value for "value" field is actually a
record too.
b: {key: (guid: chararray,sessionSkey: long),value: (guid:
chararray,sessionSkey: long,seqNum: int,sessionStartDt: long)}
my question is, how can I address the seqNum field under "value", so that I
could so filtering like this:
c = filter b by value.seqNum == 1 ;
?
thanks
Yang
