Hi all,

Just started with AVRO (in C++) and a bit stuck (so this will be an easy
question).
All examples show how to encode data and decode it right after you did
that, so you can immediately connect the OutputStream to the InputStream,
completely ignoring the size of the encoded data. However, what I'd like to
do is to send the data to Kafka, so I need to know how many bytes I need to
read from the stream. After encoding, the byteCount() of the OutputStream
always returns 4096 which looks huge for 3 doubles and a short string. When
I read back those 4096 bytes of data, I can indeed see that only the first
40 bytes are non-zeros. I cannot find any method in the Encoder or in the
OutputStream that does return the length of the encoded data. Am I
overlooking something ?

Thanks,

Olivier
