Hello everyone, I have just run into the problem discussed on SO at https://stackoverflow.com/questions/43738118/size-of-encoded-avro-message-without-encoding-it
I am using avro from C++ and currently have a payload buffer of fixed size into which I do the encode. I found that for some messages I can get an exception thrown with the error "EOF found". I worked around the problem by increasing the buffer size, experimenting with binary chop until I found something that worked without being too wasteful. But this is tiresome. There doesn't seem to be a way to find out how many bytes are required except by trying, catching the exception, and then retrying with a larger buffer. What can be done please? I note that in good ol' sprintf one can supply the null pointer for the target buffer and it will not try to write into it but will return the number of bytes it would have written. This allows one to allocate a buffer of exactly the right size. Is there any chance of adding such a facility to the C++ avro API please? -- Regards, Andrew Marlow http://www.andrewpetermarlow.co.uk
