[SPDK] Re: a distributed storage system base on SPDK

The spdk-csi is a very good reference for me. I'm looking Yibo's
youtube video about it.
About ADNN, I only find a description here:
https://www.snia.org/events/storage-developer/2020/abstracts
Besides reading the code, can I find any introduction about it?

Best regards.
