What’s your take on inter-cluster communication?

E.g. I could hypothetically have 3 clusters:

1. Administrative
2. Web-Facing
3. Backend

Potential use cases:

• Backend might produce updated parquet files which needs to be transferred and made accessible on metabase in the Web-Facing cluster.
• Web-Facing might need to send batched inputs (from webhooks for example) to Backend for processing.
