@kapa.ai updating namespace_format in destination can cause connection deletion ?

No, updating the

namespace_format

in a destination does not cause connection deletion. However, it can cause other significant issues: 1. Orphaned tables: If you change the

Destination Namespace

(or

Stream Prefix

) configuration for an existing connection, any tables previously written to the old namespace/prefix become orphaned — they are no longer synced to, and Airbyte will not clean them up automatically. You must clean them up separately. [Clearing Data] 2. Data downtime / need to clear: Changing namespace-related settings may prompt you to clear affected streams to ensure data continues to sync accurately. [Configuring Connections] 3. Stream uniqueness enforcement: Airbyte requires that stream identifiers be unique across connections sharing the same destination. If changing the namespace causes a conflict with another connection's streams, that could cause sync failures. [Stream Uniqueness] The connection itself is not deleted when you update

namespace_format

. You can update it via the UI (Settings tab), the Airbyte API (

PATCH /connections/{connectionId}

), or Terraform. [API Reference] > ⚠️ After changing the namespace, it's recommended to clear and re-sync the affected streams to avoid data inconsistencies. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
