Launch HN: Hydra (YC W22) – Query any database via Postgres
<p><pre><code>  > Hydra automatically picks the right DB for the right task and pushes down computation, meaning each query will get routed to where it can be executed the fastest. We’ve seen results return 100X faster when executing to the right database.

This is really interesting. Could you talk a bit more about query pushdown and planning/optimization?<p>Is this through FDW's? Would love to hear more about the technical details.<p>Shameless plug -- I work at Hasura (turn DB's into GraphQL API's) and this seems incredibly synergistic and useful to get access to databases we don't have native drivers for at the moment.<p>Any chance of an OSS limited version?
