(Apologies, resending with subject line)

Hi,

With the legacy datum API one could create a read record schema with a subset 
of the fields in the write record schema. And then call avro_file_reader_read 
which takes the read schema as one of the parameters. That call would then 
correctly read inĀ  just the subset of the fields as defined in the read schema. 
But I can't seem to do the same with the new API.

My read code does:

iface = avro_generic_class_from_schema(read_schema);
avro_generic_value_new(iface, &avro_record);
avro_file_reader(filename, &reader);
avro_file_reader_read_value(reader, &avro_record);

If the read schema is the same as the write schema then all is well. But if the 
read schema has only a subset of the fields in the write schema 
avro_file_reader_read_value gets an error with error string "Incorrect sync 
bytes".

Am I doing something wrong here? If so, what is the right way to achieve such a 
projection read?


Thanks.

Alan
