[Jetstream] Multiple hierarchical Subscriptions

[in-cloud-opensource]

Hi,

We are building a central component that handles deletion of data in a common way. For that, we are planning to publish a single event to delete data in all subscribers.

// use case: delete all data in all services
Publish: data.delete

Apart from that we want to trigger data deletion for a single service.

// use case: delete data for a single service “some-service”
Publish: data.delete.some-service

Is there a way to configure a consumer in way to get data from data.delete and data.delete.some-service in the same time or do we have to use multiple consumers, where every service needs multiple parallel subscribe calls

We are using the nats Jetstream

subscribe to data.delete.* and then publish to like data.delete.all or data.delete.some-service

But when I subscribe to data.delete.* I would expect that every subscriber gets all messages for every service, right? Then clients need to filter I they are interested in the message that have been published.

Yes, then you need to subscribe multiple times. Is this JetStream or core nats?

Jetstream

Yes, then you need multiple subscribes and probably for each one an ephemeral consumers. If you want it to act like all subscribers with servce service-name gets it each will need a consumer.
