Hey @jda
You can see from the code that Snappy decompression is only attempted if the datatype reported by the server indicates it’s Snappy compressed. But your cbc-cat detective work indicates it’s stored as non-Snappy.
What is your bucket’s Compression Mode setting? I’m wondering if a) it’s Active and the server is snappy-compressing on the fly and b) perhaps something’s going wrong here and that’s why it’s failing.
If it’s Active, could you try changing it to Passive and seeing if the issue is resolved? Passive means that if a document is stored compressed it will be sent compressed, but no active on-the-fly compression will be performed.
