Hi Kosala, I’ve drawn a quick diagram:
[cid:[email protected]] When you provision a subscriber, Ellis uses the Homestead Prov API to ask the Homestead Prov process to put the subscriber’s details into the homestead_provisioning database. When Sprout needs to get a subscriber’s details, it sends a request to Homestead over the Homestead API. Homestead then uses the data in the homestead_cache and homestead_provisioning keyspaces (or from the HSS if you were using one) to respond to Sprout. So Sprout never directly reads data from Cassandra: it always uses the Homestead API to get subscriber details. Does that help? These are quite detailed technical questions – it sounds like you are trying to do something different and new with Project Clearwater. I’m happy to help if you want to discuss your plans.

I am not using HSS. I am using Ellis to create accounts of private and public IDs. I saw that crest/homestead-prov is used by Ellis. When I create accounts in Ellis which store data in homestead_provisioning keyspace {implicit_registration_sets, private, public and service_profiles} and homestead_cache keyspace {impu and impi} I have the following issues: 1. how sprout is reading homestead_cache ? (using crest/homestead-prov API or using homestead API ?) 2. Which components are reading data from homestead_provisioning keyspace?

Homestead exposes its own API, separate to the Homestead Provisioning API. It’s documented in the Homestead codebase: https://github.com/Metaswitch/homestead/blob/dev/docs/homestead_api.md. Homestead is able to run without Homestead Provisioning, in a deployment with an HSS. It acts as a gateway and cache, allowing Sprout to retrieve the data it needs from the HSS. In this sort of deployment, there is no need for Homestead Provisioning, so we need to expose an API that can be used without Homestead Provisioning. That’s why Homestead has its own API. I hope that helps. Yours.

Is this using homestead provisioning API ? If not, could you please explain me the procedure? Thanks in advance! Kosala
