@Avogar Please take a look at this.

I don't see this code in upstream in https://github.com/apache/avro. Why not to make a PR to the upstream first so the maintainers can review it properly and verify it's 100% correct? I don't know this code well enough.

I don't make PR to upstream because the upstream rely on old boost version, which does not include zstd support, so will need to upgrade boost and introduce zstd library, I don't think it's easy to be accepted. But in ClickHouse, both of the newest boost library and zstd library are self contained.

The logic of zstd is almost the same as deflate(zlib).

Ok, I understood. Let me discuss it with the team
