Shameless plug: We are working on MyDuck Server: https://github.com/apecloud/myduckserver, a similar project that focuses on MySQL analytics but also exposes a Postgres port for direct DuckDB querying. Unlike BemiDB, we store data in the native DuckDB storage engine (instead of Iceberg), which is faster and does not require compaction. We are Apache 2 licensed. The official announcement will come soon, but comments are welcome!
