Hello, in my spring boot app I use MultiSchemaMultiTenantProcessEngineConfiguration to implement multitenancy. I have some rabbit listener which listens when a new tenant exists and registers it with registerTenant method of MultiSchemaMultiTenantProcessEngineConfiguration.class. I was wondering …

Hey @desp.kaz , You’ll need to implement your own logic to avoid registering an already registered tenant. I would say that it is not advisable to call the registerTenant twice from different threads in the same time. Cheers, Filip

Thanks for the answer Filip! My initial problem was that I may have many kubernetes pods(instances of the app) that should all be aware of the tenants. If only one pod calls the registerTenant method at my listener then I guess that tenantAwareDataSource won’t be updated for the others, right?

[image] desp.kaz: If only one pod calls the registerTenant method at my listener then I guess that tenantAwareDataSource won’t be updated for the others, right? Yes indeed, the tenantAwareDataSource is a based on a single node implementation. If you have a multi node scenario with a dynamic c…

Thanks! Just one last question, at my custom implementation the async executor must be created once? Or does it make sense to have one per instance-pod? I am not entirely sure how this works exactly.

It should be one per instance / pod. Otherwise, only one pod will be able to handle async jobs for that particular tenant. Cheers, Filip

you may consider using hazelcast it does many things and they are pushing it towards ML-AI as all companies do (that part I have no experience with), we use the open-source version for data-synch between kubernetes pods and that works great: Distributed Map | Hazelcast Documentation in our experi…
