zhou from mooncake labs here.

Good point! Normally for postgres extension it won't be solvable, but for mooncake it is actually not the case!

The core idea of mooncake is to built upon open columnar format + substitutable vectorized engine, while natively integrate with Postgres.

So right now it is using duckdb within postgres to run the query, but we can and we will support ad-hoc using other 'stateless engines' like Athena, StarRocks or even spark to run a big query.
