Werner Daehn commented on PARQUET-129:
--------------------------------------
LogicalType.....how is that used to "break the circular references"? I did not
get that idea. An Avro logical type is just a synonym for a datatype - simple
(like timestamp->long) or complex. But how is that related to circular
references? Isn't that more for the flattening approach??
I will have a look into it, okay. I am just so spanking new to these internals,
hence scared a bit.
