 1. **This project is in beta.** There are still some things missing or broken.
 2. **Postgres only.** Actually, that might not be totally true. Debezium has MySQL support, but this project has not been tested with it. Want to help? Give it a try and tell us how it goes.

If you're listening to `created` events, the record might not exist in the database anymore if it was deleted before your handler processed it. You can determine when an event occurred via `event.date`

 5. **Json filtering, date arrays, custom types, and replaying errored messages are not yet implemented.**
 6. **Live stream handlers can't be hosted on a serverless platform.** They need to be constantly waiting for new events to come in. Your main backend can still be serverless, and you just communicate between the two like any other service.
 7. **Only the `public` schema is supported at this time.**
