Supabase CEO, Paul Copplestone, announced an open-sourced experimental CRDT extension for Postgres named pg_crdt.
The pg_crdt extension enables collaborative app features by allowing multiple users to edit the same data, ensuring consistent final data state.
This approach provides a decentralized method where updates can merge independent of the order applied, challenging the traditional central authority model.
Current limitations include broadcasting entire documents for small updates and high overhead for large CRDT types in Postgres.
Supabase invites community involvement through GitHub discussions to refine and potentially integrate pg_crdt into their platform.
