This looks super useful for anything requiring optimistic updates, but how do you get data from triplit into another db? Perhaps for analytics or audit purposes.

With something like electric-sql you can just use one of the many Postgres tools, and other local-first options like https://ably.com/livesync have database adaptors for replication. I think this is an important requirement whenever you build your own database

[I work on Triplit] Currently, You can accomplish this by pulling from Triplit with either a JS client that just subscribes to each collection or with the REST API but we're currently working on a way to define custom "triggers" on your Triplit Server so you could directly push into any other database as you'd like

Is “triggers” a change-data-capture like thingy? Having an easy to connect to CDC stream seems like a great feature to offer. Is your trigger concept like DynamoDB Stream + triggers? https://docs.aws.amazon.com/amazondynamodb/latest/developerg...

[matlin]

Yes that's pretty much what we're going for. I'm less familiar with DynamoDB Streams but we're taking inspiration from Postgres triggers https://www.postgresql.org/docs/current/sql-createtrigger.ht...

I recommend having a pre-built integration that dumps all changes to the database in a Debezium CDC compatible format. Not sure how you'd normalize Triplit changes into Debezium updates, but something to think about. Debezium CDC format lets you pipe changes from one DB into a stream system like Kafka, and then out of Kafka into another DB on the other end. It's handy.

For example, the original method for connecting Postgres to Materialize.com was using a Debezium stream: https://materialize.com/docs/ingest-data/cdc-postgres-kafka-...

That's a great pointer seems like a many birds single stone solution!
