Frequently asked questionsFAQs

What databases are supported with Pulse?

Currently, Pulse supports PostgreSQL. We plan to broaden support to include more databases soon.

Note: Pulse compatibility with Postgres-like databases depends on their logical replication capabilities.

Can I use Pulse in my front-end code?

No, Pulse is server-side and subscriptions cannot be initiated directly within client-side code.

If you would find this feature valuable, please share your thoughts on the #help-and-questions channel in our community Discord.

Does Pulse store my database events?

Pulse does not persist database events and does not provide delivery guarantees regarding ordering or exact-once/at-least-once delivery.

To capture database events, an application must maintain an active connection to Pulse using the subscribe method. Any events occurring without an active subscription will be discarded.
