Post excerpt:
Ducklake is a new lake storage format by MotherDuck. It aims to solve some of the issues with Iceberg by centralizing metadata in Postgres, instead of directly on blob storage.

Hello Everyone! We built SQLFlow as a lightweight stream processing engine. We leverage DuckDB as the stream processing engine, which gives SQLFlow the ability to process 10's of thousands of messages a second using ~250MiB of memory! DuckDB also supports a rich ecosystem of sinks and connectors! https://sql-flow.com/docs/category/tutorials/ https://github.c
