> > ~ a billion crypto operations (meaning a billion parquet pages) > > Out of curiosity, what is the underlying cause? The AES GCM math - when an attacker has 2^32 blocks, encrypted with the same key (and random nonces) - the key can be derived from this information. Since the vast majority of blocks in a parquet files are the page headers and the pages, the limit is a couple of billion of data pages. -- This is an automated message from the Apache Git Service.
